Some people have a bunch of minor annoying side effects and others have a few
that need to be kept on top
of or they get worse.
Many people complain of fatigue, nausea, flu like symptoms (mainly after the Interferon injection), rash and/or itching, headaches, diarrhea, general malaise. Pardon my bluntness, but you may get burning diarrhea (and some have pretty bad internal rectal pain). Incivek seems to cause this flaming diarrhea along with hemorrhoids.
