when lifting the barbell for squat, the circled area felt pain.. on one side on the right felt pain

using about 65kg (including the bar)

better stop lifting for now and go get a medical checkup

How long have you been squatting?

Do a high bar back squat instead of a low bar

ok now i know.. all the while i was using high bar.. only started low bar this week

odd. maybe back muscles not there to cushion.

If you're going to change the movement you'll have to reduce the weight and build it back up. Your upper back has not had time to adapt to shouldering 65 kg.

Guess ure stressing ur backbone since its still on its soft stage. Before u damage it, better stop now. I assume ure still newbie who is trying weight lifting? U need a lot of mild exercises to strengthen ur bones before u start carrying heavy objects to build your body.

Yup

Go lighter with the weight, if pain persist, either stop, seek trainers' help, or seek doctor
