On my last set and rep on the BB incline press (225x5) My spotter noticed my left side was higher. I was grinding it out and felt slight pain in my right shoulder.
After the set I stretched the shoulder out and the pain went away. Then now there is numbness under this red ovalish circle right on the anterior deltoid.
I feel no pain but only slight numbness now after icing it for about 30 minutes.
What could this be?
