Is it normal that i have to crack my knees every few minutes?
I'm currently suffering from what is either something I truly can't help or a bad habit.
Basically, every few minutes, my knees start to ache and itch - it isn't very painful, it's like an annoying kind of pain.
I then get this urge to stretch my leg out, push down on my kneecaps and give them a good crack. The ache then goes instantly, and the feeling of relief is great. Then, it comes back about seven minutes later, I re-crack my knees, and so-on and so forth. It's now so much of a habit that it's automatic.
However, this can be very annoying when I have no space to stretch my knees out, such as when in the cinema with little leg room. This means I have to suffer the ache for an extended period. But the upside to this as that when I finally get the chance to crack my legs, the relief is even better.
Is it normal?
