I am experiencing random spells of generalised abdominal pain with some bloating and back ache lasting an hour or so and it usually responds to paracetamol. no bowel of urinary symptoms.
Thanks for posting your concern in Chat Doctor. Having constipation and bloating along with backache seem to be of colonic origin. I think you may be suffering from habitual constipation or a constipation predominant IBS (IBS-C). But, obviously they are diagnosis of exclusion (you need to exclude other serious problems). Even guardians and peptic ulcer disease may present in this manner. My recommendations will be to have plenty of water throughout the day, avoiding large meals (break your meals into small frequent amount), added curd to meal, avoiding high fat diet and avoiding diet having refined carboy Chat Doctor.  If the condition worsens in the coming days, or you have episodes of blood in stool, you need to get a colonoscopy done. Best wishes.
