My friend is suffering from headache from past couple of years. All of sudden pain get started and remains for 2-4 hours. Once she gets sleep then only she gets relief. In this condition she is not able to concentrate on any of activity and gets disturbed, even she could not eat food properly. Now it has become a regular activity whenever she is on phone or think something or doing nothing this paid gets started and she suffers badly. She has gone to some doctors but still the same issue is occurring. I am unable to find out any specific reason for the same. But need a better consultation so the she can get rid off from this pain/migraine problem. Request to please suggest us on the above.
