I think I tore more?

So I’m 6 days pp and I tore internally near my cervix. I got a lot of stitches because of it. Yesterday when I was up I sneezed for the first time since delivering and everything tightened and pulled down there and it hurt so much. Now every time I move really I have a burning sensation and pain I think I my perineal area but it’s hard to tell where it’s coming from. If also hurts when I pass gas. Could I have torn more or pulled a stitch just from sneezing?? Should I call my OB? 😩
