For as long as I can remember, I have had to deal with the worst headache on a daily basis. There was a time that I went almost a month without the ache, and I thought that was the beginning of a new phase, but then it started again. I have been to several doctors, they even prescribed medicated glasses for me in Nigeria because, according to the doctor, my eyes are sensitive to sun rays. However, the glasses yielded no result and I had to stop wearing them. What could be the problem?
