It's almost certainly due to circulation issues. Have you ever had a test that tells if your blood is too "thick"? It's sometimes called a PT/INR or INR, I think it's calls other things as well, but it's late here.

Are you up to sipping on some warm tea? You can cover up to help raise your body temperature. A heating pad would work too. I know you are having issues with water on your skin right now, or I'd suggest warm baths and/ or showers. What about
those warming gels for sore muscles? Are your hand still cracked?
Do both of your docs know that this has been happening? If not, this definitely one of those things that they both need to know about
.
Hopefully others will have more suggestions about
what you can do that doesn't include swallowing something to help you.
