Last night I was sitting on the sofa in the evening, roughly two hours after eating dinner I had Sudden stomache pain almost cramp like and at the same time and upper / mid back ache. It felt so bad I laid on the floor, then tried to go to bed, it felt worse on my side and the pain meant I couldn’t sleep for hours, it went on for about 6 hours and then I woke up this morning, a bit of residual back pain and that was it. I am completely flummoxed on what this is. Weirdly about a month ago I had the same type of stomache pain but not back pain, as quickly as it came it went again. Anyone have any idea?! Is it bad indigestion, or something else?! I wasn’t constipated just to add!
