I am facing severe pain from back side of my head to till the neck and across the shoulders and behind my ears. This pain problem is there from 6 to 7 months and I have consulted many doctors, some say it is because of the hole in my teeth (molar) which is very deep that it cannot be filled and some say it is due to stress I have taken many medicines including some vitamins minerals medicines and
vitamin b12 injections but I see no relieve. Please tell what is the actual problem and what is the cure. If it is because of the hole in teeth how to cure the hole as dentist say the hole is so long that it cannot be filled. What to do
