Tinkling, numbness, vibration feeling.

Hii, I am 23 years old. I am feeling numbness, tinkling, vibration all over my body for one year. But nowadays it's severe and I have a tinkling sensation in my head. I have a pain in my throat. I loss muscles all over my body even my face also. My skin turning into pale skin. Nowadays I have a tinkling sensation in my face. My skin is sagging. Before 1 month I consult a doctor. And taking blood, test sugar, tests B12 test. They said nothing wrong but my B12 level is low. So they provide some medicine for 15 days. I take it but no difference. The tinkling sensation numbness, vibration, loss of sensation problem still I have even severe. Afraid of my life. Also I want to tell you that I have a masturbation habit from my childhood . I can also tell you that excessive masturbation habit. So is it nerve damage? Treatable condition? Afraid of life.
