Severe headaches : Benign paroxysmal hemicrania is a type of severe headaches which are not that common. If you have consulted a neurologist, consult a headache specialist; a MRI of your brain might be needed before trying any treatments.

ParoxysmalHemicrania: is trigeminal autonomic cephalgia. PH is characterized by frequent (10 to 20) brief, intense unilateral head pain attacks daily. PH is more common in women, with an average age of onset of 30 years. The headache attacks are accompanied by lacrimation, conjunctival injection, rhinorrhea, periorbital swelling. It is an indomethacin-responsive headache disorder. Rec.: see orofacial pain specialist

Hemicrania: Hemicrania is a form of headache that is similar to migraine and cluster headaches. It normally occurs on one side, and there may be tears, a stuffy nose, or eyelid changes. It responds to indomethacin, normally the other two kinds of headaches do not. http://www.ninds.nih.gov/disorders/hemicrania_continua/hemicrania_continua.htm
