Recognizing Symptoms of Lyme Disease
Now that summer’s here, I bet you’ve already had a friend tell you he or she has Lyme disease, especially if you live somewhere in the Northeast. Because small deer ticks feed on mice, deer and humans in the late spring and early summer, this is the most common time for symptoms of early Lyme disease to appear.
So what are the symptoms of Lyme disease? Lots of people think that Lyme can do just about anything, but in fact Lyme disease causes just a few symptoms patterns that doctors can easily recognize. (Blood testing is used for confirmation in some cases.) Some people with Lyme disease complain of being tired, but fatigue all by itself is not a symptom of Lyme disease.
Early Lyme Disease Symptoms
These symptoms begin 3-30 days after the bite of an infected deer tick. Blood testing for Lyme will be NEGATIVE at this time so the diagnosis is made based on symptoms alone. People who are treated with antibiotics for early Lyme disease generally don’t develop later disease. Symptoms may include:
- Bull’s-eye rash (“erythema chronica migrans”)—this rash is round or oval, flat, red (sometimes with lighter rings inside), and larger than the size of a U.S. quarter. The rash slowly expands in size over a week or two and then goes away, even if it is not treated. Because the rash develops at the site of the tick bite, it is often found behind the knee, under the arm, at the waist, or on other warm and protected areas.
- “Flu-like symptoms” such as fever, headache, muscle and joint aches. (But cough, sore throat and stuffy nose are not symptoms of Lyme disease, so if these are present, you don’t have to worry.)
Later Lyme Disease Symptoms
Other symptoms develop within the first few weeks to months after infection:
- Migrating joint pain and swelling
- Multiple bull’s-eye rashes—these spread from the original rash and don’t mean you’ve had multiple tick bites
- Meningitis—fever, headache, stiff neck, light sensitivity
- Bell’s palsy—a condition where there is weakness on one side of the face, producing “droopiness” of the mouth and eyelid
- Nerve root pain in an arm, leg or torso—this is sometimes mistaken for a pinched nerve or shingles
- Carditis—changes in the heartbeat that can cause dizziness or fainting
Some symptoms begin many months or years after infection:
- Arthritis—usually in one knee. The knee can be very swollen, but it is usually not terribly painful.
- Neuropathy (numbness in the hands and feet) and encephalopathy (a brain problem)—this is more of a problem in Europe than in theU.S.because Lyme bacteria are different there
Remember, Lyme disease is very treatable so call your doctor if you have symptoms, but otherwise don’t sweat it, ENJOY YOUR SUMMER!
