There is something not right in the brain. Lack of concentration is there. If i am seeing something there is a pressure on eyes. I can't hear people talking continuously, there will be some kind of irritation. There is breathlessness issue. If i have to do three four things at once, will miss something. Have to focus hard. If there is a loud noise or music i get irritated. It's a mixture of lot of things. I have gone to physicians and they suggested some tests and eye test also. Have done it. Got my reports and there is a deficiency of B12 D3 and something in liver. Plus there is a power also in my eyesight. I started taking medicines and got my specs also but the problem is not going.
