I have been experiencing a feeling of dizziness and imbalance while walking for the past 4 months. It come and goes in phases and is only while walking. I get a feeling that I might fall down, although it has never happened. I visited a neurologist but he said everything seemed normal. He even gave me vertin tablet for 2 weeks but nothing changed. All the blood reports including Vitamin B12, D3, TSH etc. came back normal. For the past 1 week, I have been experiencing a tinkling sensation in my right hand finger tips. I'm not sure if all this is related. Can you suggest me what should be done and if the symptoms lead up to anything serious condition?
