Lyme disease may present as a red, expanding rash called [[erythema migrans]] (EM) along with flu-like symptoms such as [[fatigue]], [[arthralgia]], [[Myalgia|myalgias]], [[headache]], [[fever]] and/or [[chills]], [[stiff neck]], [[anorexia]], and regional [[lymphadenopathy]]. EM resolves in approximately 28 days in untreated patients. Lyme disease is effectively managed by prompt treatment.


==Prognosis==
Untreated [[infection]] may spread from the site of the bite to other parts of the body, producing a range of symptoms including neurological, cardiac and dermatological manifestations. Many of these symptoms will resolve over a period of weeks to months, even without treatment. However, lack of treatment can result in additional complications. [[Lyme arthritis]] is the most frequently presented symptom in [[Lyme disease history and symptoms|late disseminated Lyme disease]].
For early cases, prompt treatment is usually curative.<ref>{{cite journal |author=Krause PJ, Foley DT, Burke GS, Christianson D, Closter L, Spielman A |title=Reinfection and relapse in early Lyme disease |journal=Am. J. Trop. Med. Hyg. |volume=75 |issue=6 |pages=1090-4 |year=2006 |pmid=17172372}}</ref> However, the severity and treatment of Lyme disease may be complicated due to late diagnosis, failure of antibiotic treatment, simultaneous infection with other tick-borne diseases including [[ehrlichiosis]], [[babesiosis]], and [[bartonella]], and immune suppression in the patient.
 
Prognosis is mainly affected by a failure to treat in a timely manner as well as simultaneous [[infections]] with other tick-borne diseases. Sometimes, patients with [[Lyme disease]] have symptoms that last months to years after treatment with [[antibiotics]]. These symptoms includes [[Muscle pain|muscle]] and [[joint pains]], [[cognitive]] defects, [[sleep disturbance]], or [[fatigue]]. The condition is referred to as [[Post treatment Lyme disease syndrome|post-treatment Lyme disease syndrome]] (PTLDS).
 
==Natural History==
===Stage 1: Early Localized Lyme disease (3-30 Days Post-tick Bite)===
* Patients develops red, expanding rash called [[erythema migrans]] (EM).
* Flu-like symptoms such as [[fatigue]], [[arthralgia]], [[Myalgia|myalgias]], [[headache]], [[fever]] and/or [[chills]], [[stiff neck]], [[anorexia]], and regional [[lymphadenopathy]] may be present.
 
* Some people may get these flu-like symptoms in addition to an EM [[rash]], but in some, these flu-like symptoms may be the only evidence of [[infection]].
 
* Some people get a small bump or redness at the site of a [[tick]] bite that goes away in 1-2 days, like a [[mosquito]] bite. This is not a sign that one has [[Lyme disease]]. However, [[Tick|ticks]] can spread other organisms that may cause a different type of [[rash]]. For example, [[Southern tick-associated rash illness]] (STARI) causes a [[rash]] with a very similar appearance.<ref name="pmid16142659">{{cite journal| author=Wormser GP, Masters E, Nowakowski J, McKenna D, Holmgren D, Ma K et al.| title=Prospective clinical evaluation of patients from Missouri and New York with erythema migrans-like skin lesions. | journal=Clin Infect Dis | year= 2005 | volume= 41 | issue= 7 | pages= 958-65 | pmid=16142659 | doi=10.1086/432935 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=16142659  }} </ref>
 
* EM occurs in approximately 70-80% of [[infected]] persons and begins at the site of a [[tick]] bite after a delay of 3-30 days (average is about 7 days).
* Early EM may be homogenously [[Erythema|erythematous]] without any central clearing.
 
* EM gradually expands over a period of several days, and can reach up to 12 inches (30 cm) across. Parts of the [[rash]] may clear as it enlarges, resulting in a bullseye appearance.
 
* The [[rash]] usually feels warm to touch but is rarely [[Itch|itchy]] or [[Pain|painful]].
 
* EM [[lesions]] may appear on any area of the body but is present the majority of the time on the [[axilla]], [[inguinal region]], or [[popliteal fossa]].
* EM resolves in approximately 28 days in untreated patients.<ref name="pmid68597262">{{cite journal|year=1983|title=The early clinical manifestations of Lyme disease.|url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=6859726|journal=Ann Intern Med|volume=99|issue=1|pages=76-82|doi=|pmc=|pmid=6859726|author=Steere AC, Bartenhagen NH, Craft JE, Hutchinson GJ, Newman JH, Rahn DW et al.}}</ref>
 
===Stage 2: Early Disseminated Lyme disease (Days to Weeks Post-tick Bite)===
* Untreated [[infection]] may spread from the site of the bite to other parts of the body, producing a range of symptoms including:
** Multiple EM [[lesions]] in other areas of the body. Multiple [[lesions]] are secondary to [[Disseminated disease|dissemination]] and are not to be confused with multiple [[tick]] bites<ref name="pmid158674072">{{cite journal|author=Wormser GP, McKenna D, Carlin J, Nadelman RB, Cavaliere LF, Holmgren D et al.|title=Brief communication: hematogenous dissemination in early Lyme disease.|journal=Ann Intern Med|year=2005|volume=142|issue=9|pages=751-5|pmid=15867407|doi=|pmc=|url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=15867407}}</ref>
** [[Facial-nerve palsy|Facial]] or [[Bell's palsy]]
** Severe [[headaches]] and [[neck stiffness]] due to [[meningitis]]
** [[Pain]] and [[swelling]] in the large joints (such as knees)
** Shooting [[Pain|pains]] that may interfere with sleep
** [[Heart palpitations]] and [[dizziness]] due to changes in heartbeat


A meta-analysis published in 2005 found that some patients with Lyme disease have fatigue, joint and/or muscle pain, and [[neurocognitive]] symptoms persisting for years despite antibiotic treatment.<ref name="Cairns">{{cite journal | author = Cairns V, Godwin J | title = Post-Lyme borreliosis syndrome: a meta-analysis of reported symptoms. | journal = Int J Epidemiol | volume = 34 | issue = 6 | pages = 1340-5 | year = 2005 | pmid = 16040645}}</ref> Patients with late stage Lyme disease have been shown to experience a level of physical [[disability]] equivalent to that seen in [[congestive heart failure]].<ref name="Klempner">{{cite journal | author=Klempner MS, Hu LT, Evans J, ''et al'' | title=Two controlled trials of antibiotic treatment in patients with persistent symptoms and a history of Lyme disease | journal=N Engl J Med | year=2001 | pages=85-92 | volume=345 | issue=2 | pmid= 11450676}}</ref>

===Stage 3: Late Disseminated Lyme disease (Months-to-Years Post-tick Bite)===
* [[Lyme arthritis]] is the hallmark of stage 3 [[Lyme disease]].
* [[Lyme arthritis]] is the most frequently presented symptom in [[Lyme disease history and symptoms|late disseminated Lyme disease]].
* [[Lyme arthritis]] is not necessarily preceded by [[erythema migrans]].
* Approximately 60% of patients with untreated [[infection]] may begin to have intermittent attacks of [[arthritis]] with severe [[joint pain]] and [[swelling]].<ref name="Wormser2006">{{cite journal|last1=Wormser|first1=Gary P.|title=Early Lyme Disease|journal=New England Journal of Medicine|volume=354|issue=26|year=2006|pages=2794–2801|issn=0028-4793|doi=10.1056/NEJMcp061181}}</ref>

* During early years of illness, attacks of [[Lyme arthritis]] are more frequent and longer  in duration. Both frequency and duration of attacks subsequently decrease.
* There may be months or years of complete remission between each attack of [[Lyme arthritis]].
* The majority of the time, [[Lyme arthritis]] involves large joints. The most commonly affected joint is [[Knee|knee joint]], but any joint can be affected including the shoulder, ankle, elbow, temporomandibular joint, and wrist.
* [[Lyme arthritis]] manifests differently than other causes of arthritis and must be distinguished from other causes of [[arthralgias]].
* Up to 5% of untreated patients may develop chronic [[neurological]] complaints months to years after [[infection]]. These include shooting [[pains]], [[numbness]] or [[tingling]] in the [[Hand|hands]] and/or [[feet]], and [[short-term memory]] disturbances.

** [[Chlamydia]] ([[Reiter’s syndrome]])
** [[Strep throat]] ([[rheumatic heart disease]])

Overview

Lyme disease may present as a red, expanding rash called erythema migrans (EM) along with flu-like symptoms such as fatigue, arthralgia, myalgias, headache, fever and/or chills, stiff neck, anorexia, and regional lymphadenopathy. EM resolves in approximately 28 days in untreated patients. Lyme disease is effectively managed by prompt treatment.

Untreated infection may spread from the site of the bite to other parts of the body, producing a range of symptoms including neurological, cardiac and dermatological manifestations. Many of these symptoms will resolve over a period of weeks to months, even without treatment. However, lack of treatment can result in additional complications. Lyme arthritis is the most frequently presented symptom in late disseminated Lyme disease.

Prognosis is mainly affected by a failure to treat in a timely manner as well as simultaneous infections with other tick-borne diseases. Sometimes, patients with Lyme disease have symptoms that last months to years after treatment with antibiotics. These symptoms includes muscle and joint pains, cognitive defects, sleep disturbance, or fatigue. The condition is referred to as post-treatment Lyme disease syndrome (PTLDS).

Natural History

Stage 1: Early Localized Lyme disease (3-30 Days Post-tick Bite)

  • Some people may get these flu-like symptoms in addition to an EM rash, but in some, these flu-like symptoms may be the only evidence of infection.
  • EM occurs in approximately 70-80% of infected persons and begins at the site of a tick bite after a delay of 3-30 days (average is about 7 days).
  • Early EM may be homogenously erythematous without any central clearing.
  • EM gradually expands over a period of several days, and can reach up to 12 inches (30 cm) across. Parts of the rash may clear as it enlarges, resulting in a bullseye appearance.

Stage 2: Early Disseminated Lyme disease (Days to Weeks Post-tick Bite)

  • Many of these symptoms will resolve over a period of weeks to months, even without treatment. However, lack of treatment can result in additional complications.

Stage 3: Late Disseminated Lyme disease (Months-to-Years Post-tick Bite)

Complications

Stage 3 or late disseminated Lyme disease can cause long-term joint inflammation (Lyme arthritis) and heart rhythm problems. Brain and nervous system problems are also possible, and may include:
