Symptoms and Signs. Early Lyme Disease. The disease starts after an infected tick expels its salivary gland and abdominal contents into the skin of a human. In about 60-70% of cases, a rash may develop at the site of the tick bite. This rash is most often circular with a clear edge, but oblong and other shaped rashes may occur as well in response to the tick bite. This rash is known as erythema migrans or EM. This rash usually starts about 3-30 days after the tick bite.
How soon do Lyme disease symptoms occur? I had a deer tick attached to my chest when I woke up this morning. It was 19 hours after I first went into the woods. There is only a very slight reddening right at the bite area with no itching or other irritation. The tick did not appear to be very engorged with blood, and if I had to guess I would say it was an adult male based on it's size and coloring.
