It could be a Herx or...part of the co-infection list my LLMD gave me stated:
Muscle pains especially the calves; may be twitching and cramping also
It is so hard to tell what is what. Is it a Herx, is it a co-infection rearing its ugly head, is your body low on Magnesium???
I wish I could be of more help to you.
