So, what's with the ICD 10 part of the diagnosis? It's like a secret code that doctors use to identify specific conditions, and in this case, it's M75.121 - try saying that three times fast! Essentially, it's a way for medical professionals to communicate and classify conditions, making it easier to track and treat them.
Now, you might be wondering how you ended up with this lovely condition. Well, it's not just from sleeping on your shoulder (although that doesn't help), but from a combination of factors like overuse, age, and even genetics. It's like your shoulder is saying, "Hey, I've had enough of this lifting/pulling/stretching business - I need a break!"
