After a year long visits to various department and doctors we finally found that the problem faced by my mother is called "dental neuralgia". That it is not related to any tooth problems. We have been visiting a neurologist but still we haven't found any solution to control the pain forever. The pain stimulates more during rainy or chilly weathers and the dosage is changed accordingly. Is there any cure to this problem, please give an insight upon the same. Any help or contacts to such help will be great and appreciated.
