Hi Aaron,
Glad to hear the hair is growing back in and the pain is subsiding. It's great when you really start to feel human again.
As for diarrhea, I had a terrible time with ulcerative colitis for a couple of months after my last chemo. GI prescribed Asacol (horrible name!), in addition, I take Florastor, a probiotic, twice a day. I also eat Activia yogurt every single morning because I'm superstitious now and think if I stop eating it, the diarrhea will come back. I've been fine now for almost a year, still take Minocycline and Clindamycin, and pray that the diarrhea never returns. Dealing with that truly sucked.
Good luck and I hope you find something that works.
Trish
