sorry to hear... i would suggest heavily sided indica crosses for the pain doesnt really matter which strain as long as it takes care of the pain...
you could go with any northern light cross or even if you prefer for the mornings so you dont put yourself in a sleepy daze all morning you can go with a good haze like lemon haze... etc...
damn sorry about the rhyming thing lol dont know why that came up LOL
since intestinal issues most if not all cannabis due to the effects of thc cbd cbn and other cannabinoids they will all to be honest take care of the inflamation roughly the same imo...
it just becomes preference then about taste, potency, and up for sativa and relaxing more narcotic effect of indicas...
