most helpful answer i'm sorry to hear you're going through this. it sounds distressing. i have never heard of heparin causing side effects with urination but that doesn't mean it's impossible. heparin can cause abdominal pain and so it's possible the symptoms you describe could be related to the medication. you don't say how long ago you were discharged from the hospital or why you were there to begin with. i want to point out many things other than heparin could cause the symptoms you describe. for example if you had a foley catheter inserted to drain urine from your bladder this can be a source of painful urination for a while after it is removed. abdominal surgery (including laparascopic surgery) can cause abdominal pain and feelings of difficulty urinating. most of these side effects go away after hours (or at most days) after hospital discharge though. all of that said if you continue to have difficulty urinating and if your bladder becomes hard and distended (you can feel it by pushing gently with the flat of your hand above your pubic bone) you should seek urgent medical attention. wishing you well!
