Hi I have a pinched nerve/herniated disc in lower back, which I ve had since December/January 2013/2014. I have been prescribed 30mg m eslon bid, 50mg nortriptyline Sid, 10mg sevredol qid & paracetamol x 2 qid. I have been having trouble urinating, like a delay, sitting waiting for it to come & I haven t had a bowel movement for 5 days now. I have been taking laxatives the whole time as i get constipated easily. I also have focal segmental glomurel sclerosis so I can t have nsaids for pain relief. Should I be going to the hospital re anuria etc or just see GP first thing tomorrow?
