Hi.I have a little problem of these reoccurring itchy bumps.They are located on my buttocks,scrotum,ankle,thigh closest to knee.It really concerns me because of the one on my scrotum.Because they come back again and again for a few months,I hope it isn't an STD.It seems like I may be getting more as time goes on.I realize I have a few more than when it started.They come back either in the same spot or very close to it.Any info would be Greatly appreciated.Thank you.
