It's been 1 year since the giardia infection has erupted. I've taken a lot of medicines like bifilac, tinidazole, serecom, enteroquinine ,cifran etc. I stopped all these medicines after finding a lot of side effects like tingling burning sensation in the legs etc. I do find little relief but it doesn't cure fully. No stomach pain nothing but the stool doesn't look normal. Can any of you help me out of this situation. I'm too worried now and don't know how this thing would go.
