Hi thanks for your question
You have under gone Novasure abalation and now you complaint of dysurea (burning sensation while passing urine) along with bloody discharge, low back pain
All these are symptoms of urinary tract infection
Get your urine examination done to rule out urinary tract infection.
You can take a course of antibiotic like leofloxicin 500mg daily for 5 days
You should take plenty of water and alkalizers to get symptomatic relief from the symptoms of the dysurea .
Hope I answered your question,
