Can a tight bladder neck go back to normal on med and bladder training like my doc said? Or will I have until need surgery? He said try train bladder

Hormonal. Urinary/bladder problems in females is often due to a hormone problem. Get your estradiol, progesterone, LH, FSH, TSH, FT4, FT3, thyroid peroxidase and thyroglobulin Ab tested on day 21 of your cycle. Treat any abnormalities found and see if this helps over 3-6 months.
Doctor is correct. Do as your Dr advises. Hopefully bladder neck will respond to medication. Always best advice to try non-invasive methods, such as medication, before surgery. Good Luck.
