My husband has had a fever of 101.6 plus (to 102.8) since Saturday (today is monday) -- Sunday night he got the chills so bad he was shaking uncontrollably, and his knees turned blue and were cold, and his feet were cold. His skin became mottled, and that has continued -- it is still mottled tonight, across his abdomen and tops of his thighs. He has been taking 2 ibuprofen or tylenol every 4 hours, and he took 2 tylenols at 8:30 - an hour later his fever is 101.6. Do we wait til morning to go to hospital?
