I’ve actually done this repeated times. Sometimes if I bend my arm back too far, I get a sharp pain in my forearm, and sometimes even around my ribcage if I twist my entire body around.
For example, I will be sitting in my car and I will try to reach around in to the backseat to get something and I seemingly twist further than my body feels I should. OUCH!
Or, I will be taking off a coat and will bend my arm back too far while taking it off. :eek:
This morning, I was sleeping on my side and I rolled over, but my left arm was “left behind”. When I pulled it around, YOINK!
The pain goes away after about 5 minutes, although I must admit that it really hurts a lot at the time.
The lesson should be: Don’t try these things like that.
