Sometimes letting someone know that they are not alone with an issue IS helpfull.
that being said, the best way to get good advice on a medical situation is to speak to a medical professional.
Jumping on the "me too" bandwagon....I discovered a small lump in that area a couple years ago....I mentioned it to my doctor who didn't seem to think much of it.
as time passed I started feeling a pressure in that area...almost like something was pushing through the muscle and tissue...and the lump became "bigger" or at least more pronounced. I continued to mention it to my GP and OBGYN at each visit...my GP grudgingly ordered an XRAY of the pelvic area and that didn't show anything...finally after 2 years and after I complained about pain in the adjacent hip my OBGYN referred me to an Orthopedic surgeon...who ordered an MRI of the area.
I got the results yesterday, The MRI shows a fluid filled cyst that appears to be originating in the inguinal canal.
The Ortho has referred me back to a General Surgeon. They still need to do a sonogram of the area so they can determine exactly what it is and after that they can make a plan for dealing with it.
My advice to someone experiencing this issue is 1. don't freak out, it most likely is nothing to be worried about. 2. Check it out from time to time, If it doesn't get any bigger, cause you discomfort, or appear to be changing then most likely your doctor is going to tell you to not worry about it. 3. If it does start growing and it starts to cause discomfort see a doctor and request testing.
