Concern - The area around my left shoulder always feels tight.

And if I just use my hand? arm? incorrectly even a little, the whole thing becomes too numb..

I used to wear a hair loss cap, but the numbness symptoms became so severe that I went to the orthopedic clinic.

When I took a picture... I found that there is indeed a disc.

Since I stopped wearing the hair loss cap, the severe symptoms have disappeared.

If I use my arm incorrectly even a little, the numbness becomes severe, and it hurts if I don't take Geborin.

I couldn't fall asleep.

The important thing is not intense arm use, but whenever I feel like I overdid it even for a moment, it always happens.

So, I'm being careful, but is there nothing else to do but just be cautious about the disk?

Will strength training help me improve a little?

By the way, if I use my arm incorrectly, it feels numb, so I'm wondering if I can do strength training...ㅠㅠ

Is there a solution??
