Sounds like you have migraines. Do you loose part of your vision or get wavy lines? I would not recommend marijuana for headaches. It might help for a little bit but would probably then make it worse. You should see your dr. As there are plenty of good treatments for this problem. You do not want to make yourself look like a druggie or you won't be able to get good help from dr. Your only 17. Stay away from marijuana.
