My husband is experiencing pain in the lower abdomen, right groin area and it worsens if he sits. Every so often he feels a warm, heat, fever sensation under his testes. Sexual urge, active, monogamous. Experienced some dry defication and gas but now is more normal..no change in diet. He has taken 2 weeks of antibiotics, Ciprofloxacin Hcl 250 MG 28, 2xd and hasn't had relief. He was checked for a hernia and his prostate is normal....what do we check for next?
