Started after my op (appendix out last week) and I am to go back to my GP on Friday/Mon if it's not sorted itself out, but I'm just curious to know if anyone else has had this. I have no sensation of needing the loo, which means I have to remember to go every couple of hours during the day (can manage at night ok). If I leave it too long I get a sensation of pressure inside, which then reminds me, but my bladder can be full to bursting and I wouldn't know! Not incontinent at all (thank God for small mercies!!). At first I assumed it was to do with my op, but the surgeon says not and all the medical bods are a bit puzzled really.
