 [ Symptoms ] i have a dull pain in my right lower abdomen and groin it hurts when i sneeze how can i tell hernia vs muscle strain  the pain was mild i would feel it sometimes when i would start jogging but it would go away it started hurting worse two nights ago after my hockey game i am 29 and am active playing hockey basketball and running i think i have swelling not a bulge but it seems to be gone in the morning the swelling and pain increase as the day progresses [ Disease ] if the bumps are stable and have not changed or improved with treatment the next thing the dermatologist might consider depending on where on the body the bumps are is a skin biopsy to get a small sample of one of the bumps to send to the laboratory and have a deeper analysis of the skin to help determine the underlying cause
