just recently my husband came back form vegas due to air force.. and later that evenning he went to the bathroom acting strange, well later that night while i was outside he was pacing back and forth and teling me he has this hard bump near his testicals, when i askd him what he thought it was he told me he didnt know..it jus showed up like 2 days before he left to come back home...so im worried that he might have got something while over in vegas..but the next day i asked him about the bump he told me it was gettig smaller, it dosent itch him /hurt him what should i be worried about this
