Does anyone else, along with other symptoms, have chills and sweating? Along with extremely bad shaking and dizziness, fatigue, abdominal spasms today, I have gotten bad chills. I have reflux and huge amounts of painful gas on my left side. I have lost so much weight that I feel weak but it's so hard to eat because of pain and difficulty breathing. If I could just rest and get a good night's sleep, I know that would help. I am on Xanax and it only helps minimally. I've also tried deep breathing and light workouts. Today I am too weak to do that. Any suggestions? I took 4 different antibiotics in the last two months. Could I also be having antibiotic withdrawal?
