Dull pain in the right side of head

[almani]

before i start, i just wanna point out that i'm 19 years old. it's been about some time now that i get this dull pain in the right side of my head. it's right by my temples and the pain sort of contracts. the pain also occurs on the right side of my forehead. it's not really an excruciating pain but it's really dull and kind of 'dead', if that makes ANY sense at all. i also get eye pain in my right eye when this headache comes. its ONLY on my right side and no matter what medicine i take, it doesn't seem to help out. i saw a nuerologist last year and they just said that i had to get sleep and eat better. i think it's more than that. i wasn't prescribed any medications but i think i am starting to need some. the pain stays for hours. going to sleep is the onlly way  the pain goes away and sometimes the pain even carries out to the next day. i have tried to monitor my headaches so i can see what triggers them, but their completely random. i thought it might be because of my eyesight so i saw an optomitrist, got glasses, yet it still hasn't changed. if anyone knows ANYTHING please let me know i'm started to get worried.
