Hi, I have had chronic diareah, cramping , nausea and headaches for a 6 days. I had not eaten for 6 days until this morning, I forced myself to have some jelly. I have been to the Drs and they gave me maxalon for the nausea and a codeine tablet to constipate me and help with the pain. But if I don t take the codeine I have extreme pain and daireah again, I feel I am masking the problem. The question I have is I am short of breath and get exhausted just walking to the car (in driveway) and back, I also quite an annoying discomfort under my left rib. What could this be caused by?
