I found a small lump in my groin area and consulted a going for the same. She said that since I have no vaginal infection or pain in lower abdomen it might be a bacterial infection. She prescribed zifi tablets, which turned out to have really bad side effects (and no effect on my lump) and caused swelling in multiple spots in both legs (suspect erythema nodosum). It is red, very painful and causing me a lot of trouble. What medicine can I take to alleviate this. Also should I consult a general physician or another gynac regarding this?
