I had that when I was pregnant but I have never had it with lyme.
For me it was lack of salt and it literally went away when I added salt to my diet.
The article above says it is caused by mineral deficiencies and a number of other things...vitamin deficiencies, medications...
(I apologize about the link not working they never do. I am in Australia something goes missing when I try to post links on this forum.)
But you are right at the root of it is the lyme, it makes getting that balance we need harder to find because it is so taxing on the body.
Hope you find out what it is soon.
