Talk to General Physician on Headache And Difficulty To Focus

I am having continuous headache and also difficulty FOCUSING on anything or any task! I know its very general to speak about this issue. But I am being clumsy all of a sudden, so its very unusual for me. I want to sleep whole day. I am forgetting things too often. I am having difficulty in managing things (such as work). I feel extremely lazy. My family often finds me blank and lost in thinking something. Its been a week that this condition is getting noticable. My mood is sad most of the time.

I have a history of taking general anesthesia THRICE due to THREE surgeries for congenital ptosis of my left eye last year.

2 weeks ago I took PRIMOLUT N for my periods cycle. That's all. I am not taking any medicines currently.

I want to be active and overcome this headache as well which is making me feel dizzy all the time. Any suggestions?
