Talk to Immunologist on Dizziness

I’m suffering from dizziness since 10 days. I consult with my cousin (Medical specialist) and he refer me yo use Multibionta-M capsules. I have used this about 10 days but no dominant effect. When I go to study, after doing study I’ll suffer from severe dizziness. I even used “ stimatil and serc” tablet. But no effect. I also consult eye specialist but eyes are normal. Now a days I’m suffering from dizziness without doing study.
