I have extreme pain in my lower right abdomen, ER doctor says it is a cyst?

Extreme pain in my lower right abdomen started in March. After 2 visits to ER, 1 visit to OBGYN, 1 visit to Primary care phys and then admitted to Hospital I’m still in pain. ER said it is the cyst, appendix was ruled out. OBGYN said its too small to be causing my extreme pain. Hospital did check gallbladder, did an endoscopy and colonoscopy. Some minor issues were found in GI but nothing significant. My pain in my lower right abdomen is unbearable. Tramadol was prescribed, but does nothing. Other symptoms included: constant nausea, constipation, pain in my mid and lower back down into my butt and hips. Pain in lower abdomen sometimes hurts on both sides now. At times I feel pressure in my entire abdomen. Spend days with heat packs wrapped around me laying in bed or sitting in a warm tub. It has completely disabled me from any normal function during the day except to concentrate on alleviating the pain. I have had 4 menstrual cycles since this began and it hasn’t gotten any better. I have Factor V Lieden, which caused 3 miscarriages over ten years ago, but not sure if this is an issue. I need some direction before I loose my mind to the pain.
