Patient: I am a 23 yr old female and have had a lump about the size of a grape on my groin for a while, it is very painful especially when i walk.I also experience pain during sex.I’ve been to the hospital but am waiting for my doctor to refer me for a scan.it has been 2 weeks since i saw the doctor at the hospital and ive heard nothing.does anybody have any idea what it could be as im quite worried? thanks
