- Try building your search one term at a time, and be as specific as you can! Search term example: "chronic cough".
- Do not enter multiple findings such as "anemia, chronic cough, weight loss, vomiting" all at the same time.
- After selecting your term from the search results a list of possible diagnoses will be generated. If the list is too long, you will be able to narrow it down by entering additional terms.
- Do not enter values such as "heart rhythm 110" or "sodium 125", instead use "tachycardia" or "hyponatremia".

- Definition

The Lyme disease bacterium can infect several parts of the body, producing different symptoms at different times; The first sign of infection is usually a circular rash called erythema migrans or EM; This rash occurs in approximately 70-80% of infected persons and begins at the site of a tick bite after a delay of 3-30 days; A distinctive feature of the rash is that it gradually expands over a period of several days, reaching up to 12 inches (30 cm) across; The center of the rash may clear as it enlarges, resulting in a bull’s-eye appearance; It may be warm but is not usually painful; Some patients develop additional EM lesions in other areas of the body after several days; Patients also experience symptoms of fatigue, chills, fever, headache, and muscle and joint aches, and swollen lymph nodes; In some cases, these may be the only symptoms of infection; Untreated, the infection may spread to other parts of the body within a few days to weeks, producing an array of discrete symptoms;
