<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've had it for about four months now, and while it never caused me too much physical pain, it grew to about the size of a ping pong ball. It's right on that part of the inner thigh that feels like a tendon. 

The first doctor I saw said it was an ingrown hair and to treat it with hot compresses, which I did- but that didn't do jack. However, that diagnosis did make me feel confident enough to poke at it and sometimes what looked like pus from a white head would come out.

Flash forward to less than a week ago and I'm finally back home and able to see my normal doc. She thinks it's a cyst or fatty tumor and decides it's small and simple enough for her to slice out herself.  
About an hour of incredible pain even though my leg was hyped on lidocaine, she determined that whatever this is is the wrong texture for her initial diagnosis: it's hard, massive, and deeply intertwined with my leg tissue. She referred me to a surgeon who is going to put me under to take it out.

Now I'm recovering from that first "operation" (it hurt like HELL after, I've had stitches before after procedures like this and the pain was incomparable) and waiting to see the new surgeon. While my doctor was able to reduce the size of the mass by about half during that first hellscape visit, it has now doubled in size and feels tight when I bend over.

I'm meeting with the surgeon on Monday, but in the meantime- anyone have any suggestions as to what this is? Right now I've decided it's probably spiders.
