Big Lump On the Inside Of M..

I had a skin tag a couple years ago on the inside of my leg & sort of right by the lip area. I pulled it off with my fingers. Now I have this lump that is getting bigger & was wondering what it could be. I can feel the lump with my fingers & then my fingers smell. I do have ab appoingment with the my female doctor at the end of the month that I made at the first of the month to take a look at it. In the mean time, is this a cyst or what & what do they do?

IT can be a simple cyst / infection ..or even a tumour. Consult Orthopedic surgeon.

Yes, a cyst is a possibility. The doctor will also ask if you have noticed any pain with this to try and help figure out what could be causing this.
