Someone I know suffered the exact same symptoms in the late 1970s in the SF Bay Area. The woman had lesions primarily beginning in her ankles, feet, and began spreading upwards. Her ankles swelled massively. As the "disease" progressed, her joints stiffened and the pain was excruciating. Her disease was treated with acetominophin. Doctors ultimately removed the woman's tonsils -- the woman had been experiencing a minimum of 5 major sore throats (strep, strep, tonsilitus) per year for prior 3 years. Results indicated the tonsils were not repelling infection but rather containing and reinjecting infection into her body. The woman has had no recurrences since then. The doctors labelled the disease "erythema nodosum".
However, in the years after the woman's outbreak, "lyme" disease was "discovered". The woman wondered whether in fact she had had Lyme disease not yet discovered. The woman did a great deal of hiking, backpacking. However, upon more careful study, while the symptoms are similar to Lyme disease, there are parts that do not match up at all. Maybe the doctors were right in that it was related to the tonsils or even antibiotic overdose. Were it "lyme" one would suspect the numbers of infected people to be higher. My two cents.
Interesting!
