Symptoms of Lyme disease
Symptoms of Lyme disease: Introduction
The symptoms of Lyme disease result from the reproduction and growth of the bacterium Borrelia burgdorferi, which is transmitted by the bite of a tick that carries the bacteria. Symptoms vary between individuals and often, but not always, include the classic "bull's eye" lesion at the site of the infected tick bite. This lesion, called erythema migrans, begins as a round, red spot that grows larger and develops a normal skin-colored center. People who have Lyme disease may also have multiple lesions, which can also be solid red in color and not have the "bull's eye" center. The lesion or lesions may be painless
After appearance of the rash, other symptoms may develop, including fever, headache, swollen lymph glands (lymphedema) and/or muscle and joint pain. There may also be a general feeling of malaise and of not feeling well.
If Lyme disease is not diagnosed and treated promptly, it progresses to a more severe stage and spreads infection to other parts of the body, such as the nervous system and heart. This can result in potentially life-threatening complications, such as meningitis and cardiac arrhythmias. Symptoms of these complications can include high fever, intense headache, stiff neck, decrease consciousness, coma or abnormal heart rhythms. Eventually, Lyme disease also affects the joints of the body as well with chronic arthritis. Symptoms include severe joint swelling and pain....more about Lyme disease »

Article Excerpts About Symptoms of Lyme disease:
NINDS Neurological Sequelae Of Lyme Disease Information Page: NINDS (Excerpt)
early stage, Lyme disease may be a mild illness with flu-like symptoms
such as fever, chills, swollen lymph nodes, headaches, fatigue, muscle
aches, and joint pain. Symptoms appear within 7 to 10 days following the
infected tick's bite. Many people bitten by an infected tick develop a
large, expanding skin rash around the area of the bite. The rash may feel
hot to the touch, but is usually not painful. Rashes vary in size, shape,
and color, but often have a "bull's eye" appearance (a red ring with a
clear center). Nervous system abnormalities may include numbness, pain,
weakness, Bell's palsy (paralysis of the facial muscles), visual
disturbances, and meningitis symptoms such as fever, stiff neck, and
severe headache. Other problems, which may not appear until weeks, months,
or years after a tick bite, include memory or thinking difficulties or
nerve damage in the arms and legs.

Lyme Disease -- The Facts, The Challenge: NIAID (Excerpt)
In most people, the
first symptom of Lyme disease is a red rash known as erythema migrans (EM). The
telltale rash starts as a small red spot at the site of the tick bite. The spot
expands over a period of days or weeks, forming a circular or ovalshaped rash.
Sometimes the rash resembles a bull's eye, appearing as a red ring surrounding a
clear area with a red center. The rash, which can range in size from that of a
dime to the entire width of a person's back, appears within a few weeks of a
tick bite and usually occurs at the site of a bite. As infection spreads, rashes
can appear at different sites on the body.
Erythema migrans is often
accompanied by symptoms such as fever, headache, stiff neck, body aches, and
fatigue. Although these flu-like symptoms may resemble those of common viral
infections, Lyme disease symptoms tend to persist or may occur intermittently.
Arthritis. After several months of being infected by
B. burgdorferi, slightly more than half of those people not treated
with antibiotics develop recurrent attacks of painful and swollen joints that
last a few days to a few months. The arthritis can shift from one joint to
another; the knee is most commonly affected. About 10 to 20 percent of untreated
patients will go on to develop chronic arthritis.
Symptoms. Lyme disease can also affect the nervous system, causing
symptoms such as stiff neck and severe headache (meningitis), temporary
paralysis of facial muscles (Bell's palsy), numbness, pain or weakness in the
limbs, or poor motor coordination. More subtle changes such as memory loss,
difficulty with concentration, and a change in mood or sleeping habits have also
been associated with Lyme disease.
Nervous system abnormalities usually
develop several weeks, months, or even years following an untreated infection.
These symptoms often last for weeks or months and may recur.
Heart Problems. Fewer than one out of ten Lyme disease
patients develops heart problems, such as an irregular heartbeat, which can be
signalled by dizziness or shortness of breath. These symptoms rarely last more
than a few days or weeks. Such heart abnormalities generally surface several
weeks after infection.
Other Symptoms. Less commonly,
Lyme disease can result in eye inflammation, hepatitis, and severe fatigue,
although none of these problems is likely to appear without other Lyme disease
symptoms being present. (Source: excerpt from Lyme Disease -- The Facts, The Challenge: NIAID)

Lyme Diagnosis: DVBID (Excerpt)
Lyme disease most often presents with a characteristic "bull's-eye"
rash, erythema migrans, accompanied by nonspecific symptoms such as fever,
malaise, fatigue, headache, muscle aches (myalgia), and joint aches (arthralgia). (Source: excerpt from Lyme Diagnosis: DVBID)
Lyme Diagnosis: DVBID (Excerpt)
infected individuals have no recognized illness (asymptomatic infection
determined by serological testing), or manifest only non-specific symptoms
such as fever, headache, fatigue, and myalgia. Lyme disease spirochetes
disseminate from the site of the tick bite by cutaneous, lymphatic and
blood borne routes. The signs of early disseminated infection usually
occur days to weeks after the appearance of a solitary erythema migrans
lesion. In addition to multiple (secondary) erythema migrans lesions,
early disseminated infection may be manifest as disease of the nervous
system, the musculoskeletal system, or the heart. Early neurologic manifestations
include lymphocytic meningitis, cranial neuropathy (especially facial
nerve palsy), and radiculoneuritis. Musculoskeletal manifestations may
include migratory joint and muscle pains with or without objective signs
of joint swelling. Cardiac manifestations are rare but may include myocarditis
and transient atrioventricular blocks of varying degree. B.
burgdorferi infection in the untreated or inadequately treated
patient may progress to late disseminated disease weeks to months after
infection. The most common objective manifestation of late disseminated
Lyme disease is intermittent swelling and pain of one or a few joints,
usually large, weight-bearing joints such as the knee. Some patients develop
chronic axonal polyneuropathy, or encephalopathy, the latter usually manifested
by cognitive disorders, sleep disturbance, fatigue, and personality changes.
Infrequently, Lyme disease morbidity may be severe, chronic, and disabling.
An ill-defined post-Lyme disease syndrome occurs in some persons following
treatment for Lyme disease. Lyme disease is rarely, if ever, fatal. (Source: excerpt from Lyme Diagnosis: DVBID)
Questions and Answers About Lyme Disease: DVBID (Excerpt)
Within days to weeks following a tick bite, 80% of patients will
have a red, slowly expanding "bull's-eye"
erythema migrans), accompanied by general tiredness, fever, headache,
stiff neck, muscle aches, and joint pain. If untreated, weeks to months
later some patients may develop arthritis, including intermittent episodes
of swelling and pain in the large joints; neurologic abnormalities, such
as aseptic meningitis, facial palsy, motor and sensory nerve inflammation
(radiculoneuritis) and inflammation of the brain (encephalitis); and,
rarely, cardiac problems, such as atrioventricular block, acute inflammation
of the tissues surrounding the heart (myopericarditis) or enlarged heart
(cardiomegaly). (Source: excerpt from Questions and Answers About Lyme Disease: DVBID)

Lyme disease as a Cause of Symptoms or Medical Conditions
When considering symptoms of Lyme disease, it is also important to consider Lyme disease as a possible cause of other medical conditions.
The Disease Database lists the following medical conditions that Lyme disease may cause:
- (Source - Diseases Database)
Lyme disease: Onset and Incubation
Onset of Lyme disease: 3 days to a month.
Incubation period for Lyme disease: usually 7-10 days after tick bite; up to 4 weeks after tick bite.
Incubation period for Lyme disease: The incubation period from infection to onset of erythema migrans is typically
7 to 14 days but may be as short as 3 days and as long as 30 days. (Source: excerpt from Lyme Diagnosis: DVBID)
