I have taken flomax for 6 yrs after being diagnosed with bph...I have recently (6 months) been  having freguent urges but only usually urinate small amounts ! I had a cath put in wednesday after the dr saw i had alot of urine still in my bladder..he removed 1200 ml and friday i had a cysto done that showed no tumors amd no enlarged prostate ..psa is normal at 3.1 ,was 3.7 the last 2 samples taken over the last 6 months,,,the dr put a cath back in and told me to see another dr at a university for urine retention..i was also diagnosed with neuropathy about 3 months ago...im not diabetic and had many blood tests done to look for the cause of the nueropathy and also urine frequentcy  without any luck! the dr thinks its possable the neuropathy is the cause ! he can not see any blockage
