Is it normal that i have to crack my knee every few minutes?
Ok so, for like 2 years now, every time I sit down on a chair or something, after 5-10 minutes, my knee starts to get this urge, kinda itchy but uncomfortable. In order to get rid of it, I have to press down on my knee slightly and I have to stretch my legs out in order to crack it. It is pretty loud sometimes. Again, this happens pretty often, I have to crack my legs every few minutes.
This can become really uncomfortable when I am sitting in a movie theatre because there is barely any space to stretch my legs.
I am athletic and a healthy person but I dont know why my knees are like this. The cracks are loud mostly and I have never injured my knees before.
Is it normal?
