I struggled with Raynaud's until my mid twenties and then had it completely reversed by regular infrared sauna therapy! Do a search for far infrared sauna therapy near you to see if there is a local center that has one you can use. Many studies with infrared sauna therapy have shown improvement in circulation. See here for more details: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5941775/ Another idea is to consume high quality cacao (ideally organic and shade grown in it's native environment such as Central and South America). I like the products from TerraSoul.com. Multiple studies have shown that cacao can increase NO (nitric oxide) in the blood which dialates the blood vessels and should help with blood flow to your extremities. See this study for more details: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5539137/ Hope that helps!
