Not sure where to post this. I'm a 40 year old female. For the past year, about every few months I have had a dull ache on the front lower left side above my leg, I guess its the groin area above my leg. It comes and goes for a day or two, then comes back again every couple of months. Looking at it, I don't notice any lymph node swelling, but this is where lymph nodes are I guess. Not sure what else is in that area? Pulled muscle maybe? Anyway, I haven't had it checked out, and am wondering what it could be and if I need to be concerned. Thanks!
