Okay question, yesterday morning I woke up abruptly from a really bad cramp in my right leg (calf area), there is now two blue lines and I've been having pain ever since.

My leg gives out now too, like I'll be sitting for like 10 minutes and when I get up I can't put weight on that leg.

Anyone experience this, how can I help it go away??
