Try to wiggle your fourth toe and ONLY your fourth toe. Can't do it?
I think I can pinpoint the problem - your right calf muscles haven't been twitching for the last several days, and the involuntary spasms aren't somehow causing your fourth toe to curl.
It hurts, but not a lot. Very annoying, though, especially around bedtime. Typical lymphoma stuff. I guess?
(Incidentally, if anyone CAN wiggle their fourth toe by itself, I am VERY impressed.)
