Can Rgp Lenses Be The Cause Of Headaches?

I am 36 and have been having severe daily headaches for about 7 years. I have been to many doctors, had MRIs, CT scans, etc. Nothing has worked and no one can find a cause. The only link I can find is that I was diagnosed with kerataconus and started wearing rgp lenses at about the same time. Could this be the cause and what do I do about it?
