Many tests were conducted for the same like MRI, EEG and blood tests, LFT/KFT and hearing tests, CBC count, neck xray. MRI Results only the presence of sinuses and report was normal. LFT results for increased bilrubin only other things normal, KFT normal, CBC test normal, X ray spine results a mild osteoarthritis. hearing tst. also results normal. EEG test also normal. Vitamin D3 Results12.7 but after that complete the course of vitamin D3 tablet fr 2.5months. these all tst. were done in Feb 2020. I was under prescription for the past 2.5 months by neurologist & ENT. Now my dizziness is less frequent than before but I feel dizziness/vertigo once a week and still low tone noise cmg frm ears & itching as well. pls suggest.
