In November of 2011 I had and L4-L5 fusion and after 2 weeks in hospital and rehab hospital, I ended up with severe staph infection requiring 8 months of treatment to get the wound to finally close. Shortly after, I developed severe problems with bladder pain and pressure that has made life unbearable. I have had IVP (normal), cystoscopy (normal) and a urodynamics study, which showed problems with the detrusor muscle. I am on Trospium for over a year with no relief. I have a terrible time sleeping because of this and am chronically exhausted. The urologist has basically thrown up his hands and sent me to a urogynecologist. She sent me for pelvic floor physical therapy which was no help. Then I have had 4 symphathetic nerve blocks which have also not helped. Urogynecologist said scar tissue from the back surgery could be causing bladder nerve irritation. I am desperate for answers here. I have had cancer twice, and due to BRCA 1 positive status, I have had a complete hysterectomy/oopherectomy. I am having a CT of chest, abdomen, and pelvis next week. If that provides no answers, I am out of ideas. Has anyone had similar experience??
