Your doctor could be right. The symptoms fit in with the criteria required for the diagnosis of a cluster headache
.Any history of watery eyes and watery nose? There are medications available to control the headache and there are preventive methods also. What has your doctor suggested to you? Another option is to learn and practise yoga
from a well reputed ,good yoga teacher. People have reported disappearance of headaches
after doing yoga. However, this will take time.
Hope this helps :)
