Hi. I Am 28 Years Old Suffering From One Sided

Hi. I am 28 years old suffering from one sided (right) headache that usually starts from the skull and comes forward to my right eye. It usually occurs same time of the day, everyday or sometime the time fluctuates. I have been suffering from the last 3-4 years. Whenever it starts occuring it lasts for 15-20 days and then gradually it happens to low down,at the time of pain i take the prescribed painkillers by the doctor. By the headache starts again after every 4-6 months. Last year i tried the Homeopathic treament for couple of months without alternatively using any painkillers and for the whole year i didnt experienced any pain at all. But from the last 2 weeks it has started again now. Please advise
