I recently had surgery, had a nerve block instead of being intubated d/t GERD, previous problems during surgery. It has been 5 days, and the past 3 I have this feeling of being choked, or something on my neck, plus a lump in my throat. I have only been taking Famotidine20mg QD for my condition. Should I change to Prevacid for a bit till this issue clears up?
