I was prescribed amoxicillin for 2 weeks and azithromycin for 5 days. After that my heart has been racing even when resting to 130 bpm. It's been 2 weeks after my last dose. Doctors don't think its azithromycin or amoxicillin. They took blood tests, ECG, Echo. But only after azithromycin I have a raising heart. Body is shaking with pain was hospitalized for a week. No cure. Does anyone know when do the side side effects stop? I'm scared to death!!
