Back Again - Pain Worse

[addessa]

My surgery was 3 1/2 months ago. I thought I was doing fine, but Tuesday my pain accelerated (for no reason) and now I am in awful pain. It taked more pain meds now to get relief.
The pain is in my lower back and down my right leg to the foot.
My surgeon wants me to go pain management, but I can't get an appointment until January 17th.
I would like to know If anyone else has had a backset like this or is something going wrong?
Thanks I appreciate your reply.
