Lyme disease symptoms vary widely because Lyme disease can affect different parts of the body. Not everyone with this disease will have all of the Lyme disease symptoms but in general Lyme disease can cause Rash which is a small, red bump that might appear within a few days to a month mostly at the site of the tick bite often in the groin, belt area or behind knee. It can be warm to the touch and mildly tender. In the next few days, the redness increases and expands forming a rash which can be as small as a fingertip or as large as 12 inches (30 centimeters) across. It sometimes looks like a bull's-eye with a red ring surrounding a clear area with a red center. The rash, known as erythema migrans is one of the hallmarks of Lyme disease that affects about 70 percent to 80 percent of infected people.
If one is allergic to tick saliva, redness can develop at the site of a tick bite. The redness mostly fades within a week. This is not the same as erythema migrans that tends to expand and get redder withtime. lyme disease symptoms include a fever, fatigue, chills, body aches and a headache can accompany the rash. Migratory joint pain is also among lyme disease symptoms. If the infection is not treated, one can develop bouts of severe joint pain and swelling many weeks to months after he/she is infected. Knees are especially likely to be affected, but the pain may shift from one joint to another. Some times inflammation of the membranes surrounding the brain (meningitis), temporary paralysis of one side of the face (Bell's palsy), numbness or weakness in the limbs and impaired muscle movement can occur weeks, months or even years after an untreated infection. If any of these signs appear they can be lyme disease symptoms. It is important to see the doctor as soon as any of lyme disease symptoms are felt.
