Hi @johnbishop – I have been on the suggested nutrition for over one year by now, unfortunately the progression of my idiopathic, demyelinating PN of small fibres has not stopped nor reversed – I am continuing anyhow. But after realyl getting into the literature of Stem Cell Therapy, I will now travel to a Budapest (Hungary) Center for plastic surgery where they offer the S C Therapy with my own fat cells (via liposuction and centrifugal extraction of body own stem cells which are then reinjected into knees for my knee arthrosis and intravenous to address PN) – it is expensive and there is no guarantee. But with almost 80 years of age I have spent a furtune on all kind of ways and means to address my PN that it makes no big difference to try something new which is only just starting in Europe and where most countries do not allow SCT. We will see! Has anyone here done any SCT and what was the outcome?
