What Causes Giddiness, Loss Of Balance And Pain In The Temple Area?

Question : It has been almost two months now that I am having this problem. I feel of balance, giddy, pain in the temple area at times it is severe, I feel tired and sleepy.

In the month of April, I had an infection in my left ear making the hole a little small. In my last visit, the doctor told me that he has treated the swelling and fungal infection, and asked me to do steaming as well. I got cured and I did not do steaming at all, however, felt that the hole of my left ear has got smaller than earlier but no pain at all.

Then two months back, I started feeling of balance, giddy, tiredness and pain in the temple area. I got my insulin test done, the physician told me that I have a tendency of having sugar in the future and some issue with insulin so he gave me a medication for a month.. Metsmall 500 but the problem still persists.
So 3 days back I went to the ENT and shared the issue with him, he said that this is possibly happening because of the ear infection. So he gave me Verbatim 8 mg + Azithral 500 + Allegra 120 mg. It has been 2 days now since I took these medicines but have hardly seen any difference. I also got my eyes check up done and things are fine. Also got my thyroid test done, it is normal.

I am very confused, tired and worried of this... Please help
