Concerned about Cold/Burning Sensation in Hand and Lip

Is it possibly a pinched nerve or something? I know occasionally I feel tingling/numbness/cold sensation in part of my hand, and it’s usually due to a pinched nerve because my spine is misaligned. I visit a chiropractor relatively regularly for several different reasons, and it usually feels better after an adjustment.

I know with anxiety it's easy to hyper fixated on one terrible thing that someone says that it could be. I've lived with pretty severe anxiety my whole life. What's really important know is to focus on documenting when you experience these symptoms and then discuss this with your doctor. Don't take whatever someone else says it could be to heart. Don't look up your symptoms because we know how bad those deep dives on webMD can be. Make an appointment with your doctor as soon as you can and in the meantime keep track of when these things happen.
