36 male weak stream. flow test @10, but do empty bladder. told tight bladder neck - rx = flomax (tamsulosin). could this be tight pelvic muscles? how to correct?

Urethral strictures,: non relaxation (functional) or actual obstruction of bladder neck as well as posterior urethral valves can all cause weak urinary stream. Poor relaxation of external urethral sphincter/tight pelvic floor muscles can be cause. Can respond to biofeedback or medication to relax voluntary (striated) muscle. Flummox certainly can help to relieve a tight bladder neck.
