I get cramping in the right leg so far, and it is daily. I have noticed that if I use the leg more than usual it will be more severe. Also when I am relaxing, or trying to go to sleep it occurs every single time.
I also noticed that the musccles feel like they are spasming, kinda like real fast flexing. It does that all day long
I am not sure if it has anything to do with spread though. For me the spread was noticed first by pain in the area that increased over time, and sensitive skin.
I hope everything stays calmed down
