If P.T don't work and the your pain is bad you might want to consider ESI (epidural steroid injections) I have alot of people in my life who found great relief from them and avoided surgery. I know lately is a hot topic from what happend with menegistis outbreak but it seem to be more controlled now. I also think you should always exhaust every conservative treatment before surgery is even on the table. I wish you the best and hope you find pain relief soon. I know and remember how painful it was before surgery.
