How Can Headache Along With Nausea And Diarrhea Be Treated?

I have been ill quite a bit this winter. I ve had the flu twice, URI and bronchitis. I ve had an almost continuous herpes outbreak for 3 months, which is extremely unusual. Last weekend thought I had a virus again. I had a headache, nausea, diarrhea, body aches. That night when I was trying to sleep, I felt a liquid coming out of my nose almost continuously. When I turned on the light, it was blood mixed with clear fluid. Now it s been three days, and diarrhea is gone, but my abdomen/stomach is still tender and uncomfortable. I am still having to be careful what I eat and stick with bland food.
