Sorry that it's being so rough on ya.

Wish I had some words of wisdom about the burning sensation.

That is one symptom I haven't had. I do have the electric shock-like pains that feel like I'm being attacked by an invisible gnome with a taser tho.
In the winter I have to use a heating pad on my legs due to spacicity and the pain. I use the kind I can control the temp and how long it's on to keep from overheating myself. Stretching can help a little sometimes too.
I'm still mobile, even with my drop foot fun. I'm numb on my right side 24/7, intensity changing from time to time. Docs believe this is a permenant condition since it's heading into year 3 for me, and I've learned to work around it. Scary and drove me nuts at first, still frustrates me from time to time, but have accepted it the best I can. I hope it's a temporary thing in your case.
Any chance you're coming down with something? Being sick can cause the MS to go wacky for a little while.
Hope you feel better soon.
