a couple months ago i began to get sores on arms and legs. they looked like zits and of course i popped them. they came back again and again. i had been floating the river often and thus thought that it was an infection. i stopped floating the river and instead of clearing up, they got worse and a black, hard, rice like piece came out of them. they kept coming back for a week or two. now they are like ingrown hairs, no longer is there a hard thing coming out but hte ingrown hairs still continue to come.. its been months and there are not just one or two... there are around 20-30. please help!
