Hi amd71, I used to love sitting in the sun but now like you I don't look forward to this since my Ms kicked off. I find to make it a little easier I sit with my feet in a bowl of cold water, I find it helps a little. I try to persever with this because the health care professionals suggest that us MSers should get as much vitamin D as we can. When the sun finally shows it face again give it ago!

Cold Water Immersion - 10 minutes in a bath run from the cold tap (though usually when I resort to this it's hot enough that the bath will be 14-15C). I come out of those chilled. Super chilled 8-] Ideally, I'd go wild water swimming, but these days, it's a tough ask.
