Have been really sick for four-five days, first bad cough, then high fever, then no fever, but hurting all over and horrible headache. Then went to clinic, was diagnosed with acute upper respiratory infection, but warning that right lung sounded "dense", be careful of pnuemonia. Started on augmentin, steroids and cough medicine capsules. But since Monday, temp won't get above 97, is now down to 95, but have sweats, soaking pajamas and sheets at night, terrific headache and uncomfortable pain around entire middle section of body, like an inner tube of six-eight inches around my entire body, a deep, hollow aching sensation like hunger only a whole lot worse and I am eating and drinking normally. Any advice?
