Slightly off hypothyroidism topic but I have been suffering with quite severe abdominal pain on the right hand side for the last 2 months. Blood tests reveal nothing, ditto urine sample and an ultrasound scan. I am taking antibiotics (day 3 today) and fybogel as the Dr's best guess is it is IBS/diverticulitis although she doesn't really know. Possibly appendix although not classic symptoms. The pain becomes unbearable as the day goes on and I have to take a lot of painkillers. I am meant to be going on holiday to Africa in 10 days time! Has anyone else suffered anything similar and what do you do about it? Particularly frustrating as I am feeling a little better on my higher dose of thyroxine. Help. Don't know which way to turn and people on here are generally helpful with good advice so just thought I would ask as I am getting desperate.
