So glad I've found this site. I took a tablet with only a mouthful of water then going straight to bed. The following day I felt like it was stuck & by Thursday I was in agony. My GP has given me omoperazole. It's now Monday still only eating soft good - still v painful & medication giving me hideous headache. How long will this last??? Having endoscopy later in the week? What else can I do?? Thank you
