Smile Design Questions

Hello sir/madam. my age is 59, I used to get a headache in my left forehead just above the eye and whenever I get it, the pain (sharp pain like stabbing with a knife) leads to straight backside of my head (straight backside to my left eye) and have an ache in forehead and back head, and nerve getting bulge in the rightside forehead (starts from my right eye to ear), which leads to improper vision in the right eye. Thank you.
