Herniated disc, pinched nerve and numbness

My MRI shows large herniated disc and a pinched nerve causing numbness. A little history: My pain started after I did lunges in the gym and it lasted for over a year. MRI showed disc herniation, which caused sciatica. About few months ago I had a massive back spasm and after the pain subsided I've started to feel numbness, weakness (toes and calf) and tingling. My spine surgeon wants to get surgery done ASAP.

I read Dr Sarno's book and truly believe in TMS but I am not sure if I am dealing with TMS correctly. Also, have others had something similar and what they did that helped them. I would greatly appreciate advice from those who have had this before.

Also, are there good online programs available to check if what I am doing is right TMS approach?
