I had a renal artery stent procedure last week. I felt fine for two days taking Plavix and 325 mg aspirin as prescribed for two days. On the third day I begin to have nausea, burning in upper stomach area and what feels like spasms in my stomach. I stopped taking the aspirin and Plavix and started taking my nexium, bentyl and Zofran previously prescribed by in internal medicine doctor. It has helped a little but after three days and nights, I am not feeling better. I plan to call my cardiologist in the morning, didn t call my primary care doctor because she would only refer me to cardiologist. Do you think this is caused by the Plavix and aspirin?
