My dad ate cyclobenzaprine salt medicine, and had problem of urine retention after 2 doses of this medicine. And also he had problem of cervical decompression from 10 years, but everything was normal. Also, after check-up, Urethral and kidney system is ok. Urologist said it may be due to cervical decompression. But I wanna know that, how can cervical decompression can cause urinary retention in just 2 days after 2 doses of cyclobenzaprine. Can cervical decompression show its effect in 2 days after 10 years? Explain please. Your answer is important to us.
