I have pain in my lower abdomen on the left side?!

I have pain in my lower abdomen on the left side?

The pain is dull sometimes its a quick sharp pain then goes away when I raise my left leg sometimes it hurts and sometimes my leg hurts too I've been having this pain for 2 years with no answer from my doctor

I had that exact same problem, and then i went to the doctor and I had an Ovarian Cyst, which is pretty self explanatory, a CYST on your ovarys, But with the pain i had it would go back....Then it would come back awhile later, and then go away again, but yes the Pains can be very sharp, or kind of dull.
Good Luck and i hope your ok
