question: my husband has a lump between his hip and groin area. he said it is very painful most of the time and feels like it is in the vein . he said there is paid going down his inner thigh and towards the back as if it is the cyatic nerve. however after taking a steroid and antibiotic it isn t gone. he said it feels like something with teeth has clamped on to him and won t let go. he is 33 and scared he has cancer.
