What Causes Headache, Neck Pain And Ear Ache?

Hi, I have been a bit off the last month. With Migranes and headaches every few days (or they will last for a few days, go away for a few days and then come back). At the moment, I have a headache, a neck ach, ear ach on my right site and senstive to light. If feels differant to my migraines and I have litlle floating things in my eyes. also, yesterday (this is day two of the headache) I started to see something else. (you know when a camera flash goes off and you get little white spots in your eyes?) like that but it goes away if I take some time out in a dark room. it is freaking me out to be a bit honest. Also, I use ortho-k? would this be from that?
