Try taking nullo and Pro-M find them on Amazon.com
I guess they help, doesn't hurt to try(take the nullo 3X a day). Also buy safeguard body soap. It'll kill bacteria on the skin, but leaves you a little dry. Buy a good probiotic too at a store, not online cause the good bacteria could die on there way to your house. I also have loose stool along with sweating for no reason(even in winter) along with the stink.
I did the whole testing thing a year ago and came back negative for everything! No crohns, no cancer, no nothing. I'm happy I'm healthy on paper, but the docs couldn't find what was wrong with me so they tagged me with IBS. I also did the entire health freak diet for a month and took these herbs that costed 500$! It helped(slightly) for awhile but didn't cure. So it has to be some type of bacterial imbalance. If you want you can message me your ENTIRE list of symptoms and problems and I'll see if we are experiencing something similar and we can help each other out.
