Suggest Treatment For Pain In Neck And Eye After A Head Injury

in the summer 1999 i had some black out spells which caused me to pass out at work one day and i fell back and hit my head. i had to get sowed up inside the wound and outside. and since then i have been getting large lumps on the back of my head that come up and go down and cause skin tears around the area i had hit my head. and now they have changed normally the pain goes away and the lumps. but some of them have gone to my neck and the pain is still there in the left side of my head and even causing my left eye to hurt. and with this i am also very tired. like i just cant stay awake. wondering if you could help me with what this may be and if i should have it check out.
