I agree regarding the diagnostic importance of this tool (punch skin bx for SFN )
For me, it will help in treatment for the underlying cause of the SFN ( which I know I have big time)
It will also help the treating doctors in proving their case to the insurance companies to get coverage for their patients for very expensive medications.

My rheumatologist wants to treat me with Rituxan infusion, for example.

thanks for reading
