I would recommend that you seek the care of an eyeMD and have your eyes examined. This may be a migraine or could be something more serious as well. There are treatments available as this sound as if it is interfering with your normal activities.

Pain that severe should be further investigated. I would suggest seeing a neuro-ophthalmologist. Find one near you at www.aao.org
