Foot pain - treatment (lidocain, capsaicin)

Hi
I'm not diabetic but I have very bad feet pain because of autoimmune disease.
My feet looks normal but inside I feel burning and squeeze.
It's neuropathy or strong fibromyalgia.

I going to try some gel or creame, now I only take pregabalin or cannabis witch are good but not enough..
Did you use lidocaine 4-5% or capsaicin (Zostrix) ?

Thanks for any answer.
