For 2-3 weeks I have had a groin lump between my left testicle and where my left leg meets my pelvis, I went to see my GP in order to find out if there was any underlying problem. After examination, my GP said that I had an infection in my groin, it causes a little discomfort when I touch it and therefore I was prescribed Fluoxacillin in order to treat this 'infection' to no avail. The lump isn't growing but after a course of antibiotics it's not decreasing in size. I'd appreciate if you guys could tell me your thoughts? Thank you.
