Neurological issues with Remicade?

I have been on Remicade close to 2 1/2-3 years and seem to be have some neurological issues. The entire left side of my body feels like it has been in a warmer, it feels toasty warm. The skin if touched briefly feel like I have a serious sunburn and hurts like heck to touch. The right side is fine. There is no rash or vesicles present. No visually skin changes or colour changes but yet for the last 3 1/2 days it has been like that. I am sure that this is neurological in origin. What I am not sure of is is the Remicade at fault? Will this progress into something more serious?
Anyone else have weird things like this happen? Any suggestions? Although it is still cold outside here having only half a body warm is a bit disconcerting.
