After about 1 hr. , rt. foot swelled up with gout(?) Soon after all shoulders, elbows, knees, fingers, and toes, swelled and in pain. Blood tests with doctor, revealed nothing, except high level (inflamitory qoutient?). Fingers and toes still in severe pain. Taking a course of Prdnisone, w/ Percocet. Does anyone have an idea of what this might be? Also came up negative on R.A. & Lupis tests. Thanks for any input.
