Pain in Shoulders When Doing Push Ups
First, the obvious: your shoulder is a complex mess of bones, tendons, and grumpy little muscles that barely speak to each other. It’s like a ball-and-socket joint that got drunk and forgot how to behave. When you do a push-up, you’re essentially asking that joint to take your entire body weight and perform a controlled bench press. No pressure.
Surprising fact #1: Your shoulder blade (the scapula) is not actually attached to your rib cage by any bones. It floats on a sea of muscle! So when you push up, if those muscles are weak or asleep, your shoulder blade can go hitchhiking into your neck. Imagine a bird trying to fly with one wing tied to a kite—that’s your push-up.
