I m unable to urinate do to my pain medication, which is tramadol hcl 50mg and cyclobenzapr 10mg. I haven t taken them in nearly 24 hours, because I m unable to urinate. I m taking them, because I was in a car accident on July 4th, I have a concussion and whiplash. Since I haven t taken my meds I ve had some serious pain in my neck and bad headaches.. What should I do? Any tips or tricks to help urinate? Should I just go to the hospital? I do have a claim number, but I really don t want a catheter.
