Hi all! It's nearly 3am and I can't sleep because I have awfully painfull spasms in my right calve. Even though I have problems with the tendons from heel to back of knee in that leg I've never had this before. I've had suggested my potassium could be low due to the mtx but just don't know, any ideas greatly appreciated?
