My left hand burns so this will be quick. But I need help please.

According to my new pain specialist, I have CRPS due to my TOS surgery. He says I am in the early stages. I have burning arm/hand, upper back&neck pain, sweating from chest down(possibly due to hyperhidrosis surgery for profuse facial sweating and redness, sounds pretty huh?)hand weakness and I am unable to do ANY kind of activity without "setting off" the symptoms within 15-30 minutes from the start of the activity. He wants to do the ketamine infusion. I am not really sure I agree with his DX of CRPS, but we are out of options. I do not have severe pain with light touches, such as the feathers seen on video clips, and I do not have swelling or color issues with my skin. What do you think? H owever the burning can be hurt as bad as a
8 or 9 on the pain scale.

Hx: Arm burning and neck pain began in 2004, "Pop" while scanning a patient in neck resulted in Annular tear at C5-C6 with herniation at C6-C7, fusion done May 06. Dx with TOS, but they had to fix neck first to make sure.
Feeling great 6 weeks post op I went back to work as a sonographer. Had sympathectomy for facial sweating and redness, seemed to work. Arm/Hand Symtoms returned within one month of my return to work. Went in for TOS surgery. Felt great for two weeks. Symptoms returned. Only difference, I can hold the hairdryer over my head with out my arm falling down. Negative nerve study and negative carpal tunnel. Last MRI showed buldging above plate in neck at C4.-C5 Age, 38, two small boys, not working, Workers comp rejected. No disability help from uncle sam. BROKE!

Please give me your thoughts, stories, theories, and inspirations(hopefully)

Thanks.
