Throat issue. Bulge at c3 c4 c5 c6 c7!

When I eat food, I have to forcefully swallow it, and it still gets stuck in my throat. Feels like my throat is semi paralyzed. And also, I have lost sensation in my head, throat and chest. When I try to sleep, I can feel jerks in my neck n throat as if blood is trying to reach brain but it's getting blocked. It's not hypnic jerk because hypnic jerk lasts for milliseconds and my jerks last for 10-15 minutes. I cannot even feel pleasure in head and body after this problem started. Earlier I used to feel pleasure by just holding hands. But now I am not feeling any sensation. Also, I have copd since 2020. Please help me as I cannot feel any pleasure from clitoral stimulation and sex and difficulty swallowing.
