I was at the gym probably a little more than a week ago using one of the weight lifting machines for my shoulders, on the last repetition I must have strained myself too much and got a sharp pain at the very top of my neck below my skull followed by a bad headache. Now whenever I try and lift weights I get rather severe headache that lasts anywhere from 15-45 minutes and I feel kind of dizzy and lightheaded. I've been doing some research and it seems like maybe I injured the top vertebrae of my spine, but I dont know what that means im no doctor hence my being here.
If you happen to know what i did I would appreciate it so much if you could share that information. I would also like to know how to treat it, unfortunately im only 18 and still in high school so I am at the mercy of my parents and unless I really pushed them the chances of getting to my local doctors office is small, their opinion would be to wait it out, so unless necessary if there is anyway of helping my situation without having to get an appointment that would be a lot better, I am however more interested in getting rid of these headaches than avoiding the doctors office. Thank you for your help and or consideration.
