I am 19 years old. I get eye pain ( left eye ) along with neck pain in the left ( responds to neck movement ) and headache on the left side of the base of my head when I read for long durations. I sit in a posture with slightly bent back and neck. The pain diminishes on closing my eyes and sitting leaning against a wall with head and back touching the wall. I feel it is due to neck strain, but it also causes blurred vision, confusion and also blackout when I suddenly get up. Please find a solution to the problem.
