Leg pain, bowel hurt not constipation.

I have endometriosis and ovarian chocolate cysts. whatsoever I do, my legs hurt all the time ,  they hurt more when I exercise but I still exercise and walk regularly. recently my neck and right arm started hurting too. I am exercising for it too. though I follow a vegetarian diet as guided by doctor and I am not constipated, I get severely bloated often, can't pass gas and there is burning pain in bowel area when trying to poop.I can't even properly sit because it hurts the same area. are all these problems related to endometriosis? I am on pain relievers,  hormonal treatment, and several other medicines since last 4 years. the size chocolate cysts in my ovary is unchanged for the the same period. kindly guide. what should I do.
