Sometimes my leg cracks in the morning. At first, the muscle begins to strain uncontrollably, more and more, more and more, and at some point oops! as if a spring had come off inside her, or as if a tourniquet had burst - it hurts terribly, not that it is straightforwardly unbearable, but not to hiss of curses and not to roll on the bed is very difficult. The muscle becomes so hard that you can't even feel that it's yours. Do not strain it so by willpower. After half a minute, he lets go and then all day his leg hurts, as after such a good bike ride. It helps to try to forcibly relax the muscle - for example, it reduces the one that is responsible for stretching the toe, I have to protrude the heel, at the same time I cannot strain these muscles. Then the cramp may simply jerk the leg back and forth.
My legs often cramp because I work a lot at the desk.
Feelings are something like this:
The muscles contract sharply, and this causes a strong pain threshold.
Muscles are "petrified" (due to multiple muscle contractions) and any movement of these muscles leads to repeated contractions.
As a rule, it does not take more than 5-10 minutes (for me).
The pain is so strong that I laugh, but I laugh, I laugh hysterically.
When the muscles are "in order" you don't feel them for 2 minutes.
If you, dear reader, often have convulsions, consult a doctor. Seizures have bad consequences.
