question: I am a 53 year old female 5'5 145 lbs with no real medical issues except for hypothyroidism which I have been taking .75mcg of levothyroxine for several years. I have been experencing severe burning in my mouth and vagina for over a year. I was told that it was probably due to hormones and have found nothing to relieve it. Recently, I started having burning sensation and pain in my abdomin. The pain is in the area of my belly  button and also seems to follow the course of my large intestine. I recently started seeing what appears to be pieces of tissue that pull apart just like tissue with red blood in my stool. Culture for parasites was negative, had abdominal and pelvic ultrasound and was diagnosed with ibs with mucus. I had colonoscopy 6months ago-normal. I also noticed a fishy vaginal smell and when cultured resulted in Strep B. I have been on antibiotics for a month with no improvement in symptoms or 3 culture results. I can't help but think that all of these things are related-all mucus membranes. I think I must have some deficiency which has now resulted in the infection. I would appreciate any help. Thank you for your time.
