Hi doctor. I'm 27 year old male. I was on unprescribed anti biotics ( augmentin) for like 3 days and later on I started using amoxycilin and penicillin for no just cause. Since then I have been feeling nausea, diarrhea, sore throat, muscle and joint pain, and low grade fever. Though I had 2 different unprotected sex contacts last 2 weeks. I have been so bothered and i have been wondering if it's the anti biotics side effect or viral symptoms. Moreover , I stopped taking the anti biotics 5 days ago and I've been taking paracetamol and vitamin c; since then the symptoms Is relieving me bit by bit. Help!! Thanks.
