Good Afternoon Doctor, I Have Few Questions For My Head.

Good afternoon Doctor, I have few questions for my head. Begin of Feb I start dizziness. There were 2 times I felt blood ran to brain. IN that moment my blood pressure pretty high. around 160/90. my weight was 116kg. After I came back Australia from Thailand at 5/3/2016. my weight gained to 118kg and the dizziness still on. End of March, I went to see my GP. He mentioned I am too fat, so he gave me Forxiga for lose my weight(I don't have diabetes). 5/4/2016 I went back to my GP for my chest had a little pain. He checked my ECG no problem, but my blood pressure was 155/101, so My GP gave me Olmetec 20mg. I felt dizziness in that night when I play basketball. 6/4/2016 I felt tired, so I went to bed early. 7/4/2016 8am I felt tingle of my back head. I did not eat breakfast. 10 am my hand and feet felt tingle. my head was dizziness. my friend rang ambulance for me. Ambulance checked my blood sugar was 5.8(I ate a fruit bar before ambulance). I went to hospital, the doctor check was no problem. He mention it was medication side effect. my GP want me stop Olmetec at 8/4/2016. I stop Forxiga at 9/4/2016. 10 and 11/4 I can't sleep, because my back head like heart beat. 11/4 I went to emergency, the doctor check was no problem. I felt dizziness until now. I did blood test and urine test for my kidney, Ultrasound for liver and kidney, Brain CT scan. no problem but the dizziness still on. last week I got flu, my dizziness changed to unbalance. now I feel my back head heavy and bloated. sometimes my top head, neck and back head have a little pain. when I change position quick my head feel dizziness and face tingle. my hand and feet feel no energy. Is it my brain have problem?
