Flap Surgery Done. Advise and help.

I have had serious teeth irritation and sensations which led to dental flap surgery 2 months back. I consulted 3 doctors before proceeding with the surgery for second opinions. Post surgery, irritation is somewhat relieved but not sensations. Sensations comes across teeths. Although i had minor back neck spasm along with teeth irritation, i did not pay more attention on neck. After the surgery, i still have sensations to cold, hot or spicy items. Difficult to drink even cold/hot water. I have used all types of desensitized gel, mouthwash and toothpastes with no breakthrough. I have noticed that neck spasm happens along with the uneasiness with the teeth. Also i have showed up an orthopedic doctor with an xray thinking this could be from neck/spine. But xray was neat, there is no major irregularities. I am worried as 2 months have already past surgery, and there is no relief yet. Sometimes i wonder if this is aftereffects of surgery. Please advise and help.
