First of all
! I am so sorry you have to deal w/gall bladder attacks... I dealt w/them for 3 months before i even knew what they were! I found that a heating pad helped me a lot when i was having an attack--- I would put it on my side, kinda under my arm pit but lower where it hurts AS SOON AS I FELT THE PAIN coming on! (mine started out feeling like a running cramp) I would lay on it and try to sleep... it helped me w/all of my attacks but 2! the two that landed me in the ER. The things I absolutely had to stay away from were:
Peanuts
Chocolate
Cheese *any kind!!*
Coffee
Greasy foods
Fatty foods
*oddly enough chicken also sent me into an attack too... and my attacks were usually at least 8 hours after I ate whatever triggered it... (i usually got them in the morning)
I basically ate oatmeal, toast (dry), pasta plain w/a little salt maybe...
Good luck with getting an appointment w/the hematologist...
I hope you can find comfort until you can get the evil thing out!
