I have been dealing w/ this for 2 years, at first I thought it was massive bug bites, about 15 mins after my period starts I get terrible sores/hives some are the size of softballs, they are raised,red , painful, itchy, they stay for a few days, then the red and swelling go away, but they heal black and look like bruises all over my legs, and come back in the exact dames spot every month, I have seen a billion drs and specialists and gave had tons of tests, biopsys and blood tests,no one can give me any Answers, I have went on birth control this month, and I have not gotten this outbreak yet, is there anyone out there that is experiencing this?
