Q. I have terrible pain in my groin area when i try to walk. Any clues?

A. Well, first of all, it depends on your gender, since men and women have different things in their groin...

Is the pain aggravated by coughing or straining? Do you feel any bulge?
In this case, it may be an inguinal hernia, which is quite common in men.

Q. A lump in my armpit Hi, Last week after the shower I found a small painful lump in my right groin. I went to see a doctor and he prescribed me some antibiotics. I’ve been taking it for 5 days and the lump is still there. I’m 31, usually healthy and work-out in the gym regularly, don’t smoke or use drugs and don’t take any medications. Is that dangerous? Should I go and see another doctor?

A. What you describe sounds like enlarged lymph node. The first diagnosis that’s suspected in such case is an infection that makes it painful. The antibiotics you take need several more days to act, so currently it doesn’t sound suspicious. If the lump persist, it’d be wise to consult you doctor
