I sustained a hard fall four years ago and did damage to my back. About 2 1/2 years I started to have problems with my sciatic nerve and at this time I started to have urgent urinary incontinenece. I am d=seeing a urologist and taking meds, but nothing seems to help. I had a spinal fusion done in July of this year hoping it would help. I suspect this incontinence is due to my back injury.
