Shoulder blade thing

[shadow1768]

Well yesterday I was trying to show something to my friend on my arm and I had my book bag on. So it involved showing my shoulder to him and I tried to stick my arm through the inside of my sweater and I made it but it started hurting, where the bone is that you can stick out your back, well I can at least. It hurts (not the bone) a little now but now I feel like I can extend the bone outward much more than before and now am wondering if thats bad? Like I can feel the difference between both shoulder blades on how far I can get it out.
And since am touching on the subject of shoulders, I can do this really cool thing with my shoulder, its like in the middle of dislocation and not, I can make a hole in my shoulder, like indnet it. When I do it while its on theirs almost no movement possible with my arm until I put it back to normal. Am wondering if doing that can be harmful in anyway to me in the future and why is it that I can do it.

Yea I know its alot but this really as me wondering alot lately. Thx for any help!

My friend can do that to. She can also put her hands behind and hold onto her hands and then rotate them completly around so they touch ehr stomach but not letting go of her hands its weird.

Just to be safe, you really shouldn't do anything with your joints or body in general that it wasn't meant to do.

Yes I agree with Red. One of these times when you do that it's going to come all the way out and it's going to hurt when the doctor has to shove it back in.
