You possibly could have a cyst. My sister, had a similar experience about 10 years ago. It turned out to be a benign cyst. I do agree with Liz C that you should go see a physician about this. good luck.
does your pain come and go not really on a schedule? does it feel like the size of a nickle? numbing pain but also sharp. im 21F and have been having this pain for a couple years with no answers...just looking to see if maybe there the same.
thanks Tasha
Your question would be better answered by a physician.
