I think I agree with the others. This may be a way of your body telling you it is tired. I have ringing in my ear and a headache all the time. I have not pin pointed when the ringing get worst, but I know I notice it more at times. Everything does get worst with fatigue or overdoing it. The double vision may be a vision issues which is fairly common with concussions. Do not go to a regular eye doctor, they can not diagnose this issue you have to go to a neuro opthomologist.

Good luck, let up know how you are doing.
