My father has been having episodes of sweats, nausea, chills, with no fever. He has gone to the hospital and had tests ran. No complications with his heart, no kidney problems. It has been going on for about 3 months now. His WBC are 13, 000, (he's in the hospital receiving atb), he is somewhat anemic. There is nothing in particular that we have noticed that brings it on. He was on Lyrica, Cymbalta, and Hydrocodone (for severe leg pain), but got off because he thought that might be causing it. So far, nothing has helped. Any suggestions? Thanks
