Bad health condition. Is very bad.

It started with a flu in Nov 2017 and after I was feeling bad so I went to the doctor, he gave me tablets and later I was feeling a kind of dizziness. And some days later it became serious. So I met an ENT who gave me tablets against vertigo for 10 days but still... I travelled out of India few weeks later and went for a CBC, it shown an infection. The doctor gave me antibiotics for 10 days after 4 days the dizziness was going away slowly and the 8th day it came back again. I went again to meet the doctor he ask me to complete the treatment and wait for 4 to 5 days and do a CBC again. I did so and then was showing an Infection again and gave me antibiotics more stronger, so I took Azee for 3 days after I felt a bit better but the dizziness was still lingering and some days later I got brain nerves issue and I went for a Brain MRI. Nothing! Till now am having nerves problem. The right part of my head pains me, a kind of pressure, my health condition is very bad.
