Burning pain in pelvic, lower abdomen & intestines. No fever
I’m experiencing burning pain in the pelvic area for the last couple of months as well as in the very low abdomen area, and lower back, bladder and intestines. It improves when I’m up but gets worse when I’m sleeping. It also improves after a bowel movement or when I empty my bladder but I don’t have a sense of urgency to urinate. I had a hysterectomy (everything) removed years ago so can’t say it’s anything like that. It feels like fire in all the areas described. I’m having a hard time sleeping and feeling tired as a result I have not had a fever. I moved here about 4 months ago and have not found a doctor. 46 Female
