On my last GP appointment, the doctor I saw told me to take a double dose of ibuprofen for pain. I explained to him that my pain was severe (8 out of 10!) for 5 days of each month, so I don't feel suggesting ibuprofen is enough! I'm going to make another appointment, but wanted peoples opinion on it first. I did have gastritis for a year and a half, but that was 2 years ago now. I have been told I can take lansoprazole to protect my stomach.
