Advice for pain!?

Linzy

Almost 28 weeks and have severe pain under right side of my rib that runs around to my back. It burns!!!! Doctors thought it was gallbladder but after changing diet for over a week and it got worse, I had an ultrasound done that showed liver and gallbladder were fine. I do have fluid around right kidney and it is supposedly inflamed but they don't think that's the problem. They are now saying it's musculoskeletal pain. I'm taking 1000 mgs of Tylenol every 8 hours as told and doing heat and ice about 80% of my day. With being a teacher it is very difficult to manage the pain. The only relief I can get is laying on my left side for about 15 minutes or almost lying flat on my back. The relief is very temporary. There has to be something else I can try, because this baby is only going to get bigger which I know is going to make pain worsen. 😭
