That's good. But, if you're having these sorts of problems, I'd strongly recommend ditching the weights and just do bodyweight squats when you get approval to do squats.
And hold off at least long enough to ensure you've got full range of motion. One of the downsides of barbell squats is that they don't permit the full range of motion. Proper squats should result in your but hitting your calves. Which is impossible to do with a heavy barbell. I can't do those yet, but I'm working on it.
Seeing all those elderly people in China capable of squatting down like that for long periods of time with no apparent discomfort made me realize just how maladapted I am.
I agree, squats have to be done until you hit your calves, but not everybody has the mobility for it. Luckily I do :).
I can do the full range, but I feel a slight discomfort when straightening the leg. Oddly enough not anymore when squatting but when I get up from the chair after a few hours in the office :D.
I usually don't train with too heavy weights, I'm not trying to get bulky, I usually try to loose my belly :D. So I do mid-low weight and high rep exercises. Also I prefer front barbell squats and hack squats more than regular ones. Though I do both or all three. The stability is much better with the former ones.
