It is my understanding that your doctor can prescribe hemorroid treatments by prescription. Since the OTC stuff isn't working, you might talk to the doctor who diagnosed you with IBS.Hemerroids and C are a common belief. I have always suffered from D and have always had hemorroids show up on colonoscopies, but was lucky that they didn't bother me too much. Have just started riding a bike for exercise and am now very aware of the darn things.Hope you get some relief soon.Christine------------------If a toilet is my throne, I want a padded seat!!
