After having my wisdom teeth removed, I began to develope red blotches on my legs, arms, fingers and toes. After two days, the blotches turned dark in color and i developed an extreamily painful arthritic like pain that lasted for 2 days. The pain was so sever that i couldn;t walk and was unable to bend any part of my body where joints connect. What could this be? 2 years earlier while vacationing, i but my foot slightly and my legs broke out in red blotches, but there was no pain. what could this be?
