Hi everyone, having a bit of trouble while running. I'm getting really bad pain on the inside of both legs just below the calves. Gets so bad that I often have to stop mid-run and stretch off. Once I'm back home, they fell very very tight and its hard to even walk. Just wondering if anyone has any ideas/solutions? Would a good pair of in-soles help? Also, I'm not sure if I'm running properly (which might be causing the pain). Seem to be landing and taking off with the ball of my foot and I remember hearing that that's not too good. Any advice would be much appreciated. Thanks.
