Hi I saw the GP Fri and given antibiotics for suspected sinusitis- prone to them unfortunately. I started taking them yesterday after I began to feel worse- 500mg Amoxcillin been on them many times BUT I don't think they're agreeing with me. Symptoms seem worse as do I. I'm still very hypo due to pooling, possible RT3, adrenal fatigue. Poss Hashimotos and hypo parathyroid. What would anyone advise? Is it possible it's not a bacterial infection and I'm making myself worse taking them?
