You see this has me curious. I’ve thought for many years that my limb afflictions have a ‘circulatory’ component involved. Your description of the neuropathy you suffer only serves to convince me more of this because I know that your main bodily organs are served first, with available blood and your periphery (for want of a better word) gets what’s left. A muscle starved of blood therefore starved of oxygen and nutrients, whilst also loading with toxins which it can’t ‘offload’, is gonna misbehave and spasm, twitch etc.
Even at the height of summer I need extra layers of clothing, today being a fine example it’s August, yet I’ve had my fire on, my central heating on and I’m typing this with fingerless gloves on, a fleecy jacket, long trousers, over my legwarmers, over my support hose!
I rest my case.
