Reynauds, gloves and socks

Dh has a battery operated hand warmer. He has heated insoles for shoes that last 8 hours. It’s important to make sure anything you buy does not get too hot.

I manage with thermal socks over my ordinary footwear (usually thick tights), plus fingerless gloves that DD knits for me.

I also make sure my legs and arms are well wrapped - thick tights as already mentioned and long sleeved thermal vests.

You can get good gloves from Raynaud’s disease.com, I wear them and heatgen socks from M&S.
Hot Hands and feet packs are good for outside, readily available at Amazon
It’s a miserable thing to have.
