I did not read the many previous postings (I'm in a rush) so I might repeat what is in there.
Nausea is bad liver function and your body is telling you to get a Liver Flush ( Hulda Clark e's every second week is a good and cheap solution).
When your liver is too weak to kill the bugs in your stomach they go down to your bowels and proliferate, your metabolism will react with diarrhea. Raw vegetables is a good way to avoid too much bugs and let your bowel get better. Go raw for a week or so. Plus, your bowels being highly irritated, aloe vera juice would be a good idea.
Armpit: lymphnod location. Your immune system is behaving. Each time I get a small armpit ache I know it's time to take vitamin C to help with oxydation. Alos, to help boost your immune sytem; echinacae is something to consider.
