Edometriosis

Patient: I was diagnosed with endometriosis in 2012. I had a small lump in the muscle(i assume) to the right of my bikini line. now the lump is about the size of a golf ball. I was place on oral contraceptive with the hope of shrinking the mass. after my period the pain gets so intense. I am so worried about the growth of this mass…the pain is everyday- constantly/…. what do you suggest? help!

Symptoms: pain in mass
