Hi, thanks for posting. According to me, your problem is related to the neck. You have developed a condition called spondyloarthritis cervicalis which consists of a damage of the neck. This has come as a result of your lifestyle, your posture and sedentary life. Your symptoms are related to a reduction of the blood circulation in base of the brain. This blood comes from the arteries that originate from the neck.
I recommend x-ray imaging to find out if your neck has this problem. After that I recommend physiotherapy
, and lastly it is important that you consult your neurologist
. Keep safe!
