Pinched Nerve in my Neck

[yue]

There's a pinched nerve around C5-T1, basically been debilitating my shoulder for the past year. It's gotten really bad the last month or so and I can barely do anything without it killing me. How tf do I fix this stupid shit

I'm thinking it's specifically C5 because I can only feel it in my rhomboid/lower neck
