cayenne pepper and face tingling

I want to share that after I decided to stop taking Neurontin (prescrbed by a Neurologist) because it was affecting my kidneys. I did some research founding that there are several creams that can be apply on skin for numbness sensation. These creams contain capsicum which is also in cayenne or any pepper.
I did have some numbness tingling, crawling sensation on my face, and also on my head.
I decided to try directly cayenne pepper on my face (because of difference in price cream versus cayenne pepper). I been applying it on my face for 2 weeks and I can say that I saw good results the next day of first aplication.
I still have a minimum of the bad sensations.
I am planing to do this for another week.
If anyone has any suggestion is welcome.

Thanks
