Hello,
Welcome to the ehealthforum and I am really glad to help you out.
Hemicrania continua (HC) is a persistent unilateral headache that responds to indomethacin. It is usually unremitting, but rare cases of remission have been documented. Although your symptoms are suggestive of hemicrania continua, but the possibility of cluster headaches which are usually repetitive should also be evaluated.
Try OTC medicines like aspirin or acetaminophen. For headache pain that cannot be controlled with pain relievers, antidepressants, beta-blockers, or anticonvulsants may be prescribed. Use a cold compress to the area of pain, rest in a room with little or no sensory stimulation (light, sound, and odors) and withdraw from stressful surroundings.
If still the headaches persist then please consult a neurologist. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
