Hi. I have been on duromine 15mg for 1 week today. I have had pain in my lower back, right side more than left. The pain also mirrors in my front abdo area. It has been constant for 2 days. I have been consitpated also although I have began a course of natural bowel openers for this as of today. Is the pain a result of this or is there a chance of renal issues with duromine? My urine is normal, no fevers or side effects felt from the medication.
