Lyme Disease

What do you think? The Doctors, Nurse Practitioners, Dermatologists, and Janitors at U Penn think this might be what Larish has. Do you concur?
He has had a blood test, and is now on his third antibiotic.
My guess is it is Lyme Disease, and the headache is what tips "Precious" off. (Anyone read the Ladies #1 Detective Agency"? I AM Precious) Mind you, I am making my diagnosis from 2000+ miles away.
I would post the pic, which almost matches the internet pics I have found, but frankly, it is too gross for the general blogosphere!

Here is the CDC scoop:

Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans by the bite of infected blacklegged ticks. Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans. If left untreated, infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks; laboratory testing is helpful in the later stages of disease. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics.

And this is the part that freaks me out the most:

Most cases of Lyme disease can be cured with antibiotics, especially if treatment is begun early in the course of illness. However, a small percentage of patients with Lyme disease have symptoms that last months to years after treatment with antibiotics. These symptoms can include muscle and joint pains, arthritis, cognitive defects, sleep disturbance, or fatigue. The cause of these symptoms is not known. There is some evidence that they result from an autoimmune response, in which a person's immune system continues to respond even after the infection has been cleared.
