In 1996, had a mysterious, bullseye rash on each thigh, and
each buttock. I tested negative for Lyme disease
, lupus, and
HIV. In 1998, I had dull, but severe pain in left arm and severe anxiety, sweating, and breath shortness for a couple hours. I recovered and didn't see a doctor then. Shortly after that, I developed an occasional very strong palpitation, only one at a time, about once a week. Then, a couple times, I had long runs of them for hours.
