I run a constant low grade fever. Sinus headaches, ear ache, body aches, nausea. ENT sent me Rx for Clindamycin HCL 150 MG. Felt better at first, diarrhea is severe, bowels are liquid and stomach burns. I dring a lot of water and getg some relief. I have dropped 7 lbs in 3 days. My chest hurts...heart? Do I continue antibiotic? I have been going to Dr for past 2 years. Never sees any fluid in ear, however when I was 6, my eardrum burst and ran puss and blood after the Dr. could not find anything... said did not think I had mumps.. did not see infection in ear. What is going on. Constant ringing... fatigue going from wanting to sleep all thetime to unable to sleep.
