I feel as if there is pain at the backside of my eye balls.

Hi,
Thanks ultimately i got a forum where I can discuss my problem.
                                                                                            I am a 25 years male. For the past many years (6-7 years) I have been experiencing pain at the back of my eyeball. Its very hard to describe the problem to a doctor as they do not take it seriously.
                                                                                          When I was in school at the age of 16-17 I used to take a sleep in the afternoon for 2 hours from 2 -4 or so in the next 3 years. I can blame to my school timings which could permit me to have a sleep in the afterrnoon.The situation becomes so worse that if I was at home I could not live without taking a sleep in the afternoon. I didn’t attend the telephone call of those who called me in the afternoon. The afternoon sleep was so sweet for me. I used to get very relaxed taking afternoon sleep that i become habituated for it.
                                                                           Then came the college part of my life which didn’t permit me to have the afternoon sleep. Those were the days where I could recognize that I had been addicted to the after noon sleep. When I used to be in the college I could realize a severe urge to sleep; and since it was not possible to do so I used to feel a pain at the back of the eye ball and a minor headache also. When in the evening I reach to my home and press my eyes manually with my hand, I felt a bit relaxed as one experience when is having a hand or leg ache. Now if it comes Sunday, I never used to go anywhere to enjoy my Sunday rather I would take a sleep and feel relaxed. It implies that if I take a sleep such a pain would rarely occur. This goes for over 4 years. I had to bear the same pain and the uneasiness to do any work in the afternoon time.
                                                                                                                 I had my good days in the college time when it was the part of preparation leave and the exams every semester. I used to enjoy preparing for the exams in the morning and evening or late in the night but not in afternoon time between 1-4 pm.It was my time to sleep. This sleep had greatly influenced  my life that any suggestion including to wake in the afternoon was damn for me.
                                                                                           This is how I completed my engineering for the 4 years duration.
                                                Now comes the time to search for the job. Again i got suitable duration to take a afternoon sleep. I used to be worried for the job but i could get a bit relaxed before sleep by thinking of that “I would prepare and study for the job” after taking the sleep.
                                                                                                                        The problem persists. I feel a pain at the back of the eyeball and when i press the eyes with the force which  we apply for a severe headache or a backache to my eyes I feel a  bit relaxed. I am in job now. still when I am in the  office i still feel a urge to sleep. The problem is that i can not sleep in the office. on Saturday and Sunday I  definitely sleep in the afternoon.
                                                                           If anyone wake me in the afternoon sleep i feel very much angry relative to one who wake me in the night. I don’t have a sound sleep.if i am sleeping and if you switch on the fan,i would wake up. I wouldn't feel sleep perhaps for the next 2-3 hours and after that the same pain at the back of the eyeball is felt and i feel something i cannot express. I feel lazy, I feel uncomfortable to concentrate, I feel uncomfortable to read, i feel to have a hazy sight.
                                                                              This pain does not get away if I take a tea or  have a walk in the afternoon in the office.
                                                                               Some times I feel that it would be better for me to work in a place with different timezone with difference of 12 hours.It would be night there when it is day here.
                                                Please give a suggest a suitable remedy for my abovesaid problem.
I would be greatly obliged to tell you more information.
