I am facing this issue from last 1.5 months. Sometimes its mild and sometimes its severe. I tend to loosen my balance a bit (very light) while walking. Like we feel when we get down after a long train journey. And feel like same what i feel after having 2-3 drinks. Little head heaviness, little weakness and lesser balanced. My vitamin B12 reads 221, D3-15.8, tsh 3.09. Brain mri is normal. Ear test is normal. The other physical test done by moving fingers before eyes and lying down getting up is normal. I m on lumia 60 and bio d3 max. Suggestions please? Any supplement or test i might need?
