Magnesium and calcium, either sometimes works to relieve muscle cramps. I find the more usual to find and more expensive mag oxide works maybe a little better, but the regular helped me a lot. If heat helps (although with what Simplystar said, maybe it's not best), but there are socks made for winter sports with battery backs that can last for hours while you sleep. I know someone who used it for their neuropathy when the baths got too time consuming.
Hope it feels better soon.
the old adage works well with any pain cold scatters heat draws with Leslee soaking her feet in hot water is what brought on the blistering with the doxil ice is uncomfortable but it does scatter the pain. She was on topotecan for just 2 rounds and her neurapathy was terrible. did they give you and pain medications. Good Luck Yvonne hope the pain eases up for you.
