Vitamin d deficiency. Get rid of this.

I have this tingling sensation on my head and sometimes a pulsating /radiating feel (both symptoms are mild, but are persistent), so I have consulted some neurologist and the medication only gave me a 50% releif, still I feel the sensation. I have been suffering with this for almost 5 months. Rarely, I feel normal nowadays. I went for cbc test, looked normal. Went for CT, looked Normal. Finally I tested for d3 and B12 levels.D3 was 14.5 ng/mL which indicated deficiency and B12 was 390 pg/ml. Now Iam in medication of these. I don't know whether the painkillers seems working or not but that radiating/pulsating feel has improved like 90%.So I wanted to ask you about this that whether this sensation happens to me because of this or any other. Kindly help me out and suggest a way to get rid of this. Thanks
