Problem is waking from priapism several times per night. Problem has persisted several years when I have pain in neck and shoulders. it started before Cervical fusion and eased up some after recovery from surgery and came back after shoulder surgery and eased up some and now back again after another shoulder surgery. I have seen urogligist and neuro suggeon they think it was caused from medicine(trazadone) but I have not had Trazadone for 4 years.
