I have one red bump on one leg that is slightly raised. It has a white area so I tried "pop" it...it just bled. It itches only sometimes. Hair grows out of it. It does not hurt, it has never gotten bigger or smaller in the 6 or 7 years that I have had it and it is not bothersome in anyway except that it is not pretty. The only thing I can remember ever happening in that area was a wasp sting sometime before it showed up. If anyone can give me a bit of insight as to what this is and what I can do about it that would be great! Thanks!
