Bh,
Don't be embarressed to call the doctor about these symptoms. You need to find out whats going on and get some relief.
I had adnomyosis which is endometrosis inside the uterus. My periods were awful. I would hardly bleed(but would spot between periods, had terrible low back pain and it felt like my insides would fall out when I stood up. I lost alot of weight when I had it and at that time didn't have alot to loose.
When I had my hysterectomy I felt so much better. I did get 3 opinions before the surgery though since the only sure way to tell if I had adnomyosis was by removing the uterus and cervix and do a biopsy. All three doctors gave the same dx so I went for it and was so glad.
Hang in there and get more opinions and more answers. Please keep us updated. Take care and rest as much as you can. You are in my thoughts and prayers.
((Hugs)) Babs
