i was flexing the other daylight, i strained my shoulders all the road down and then strianed them forward, towards the front of my body and I pushed them within really hard. I get a pain within my sternum but it went away after a couple second. I've flexed like this multiple times.. The twinge is not always at hand. I am afraid I bent my sternum in or something.. Or I broke my sternum. I'm not sure but it worries me. Is it possible to bend your sternum inwards ? please consent to me know, thanks.

I other have cramp?

If you bent your sternum you wouldn't be typing.
