Patient discussion about band.

Q. how bad can your headaches get the ones i get feel like a band around my head and my eyes ache.

A. Headache can be very painful; thankfully, headache chronic syndromes can be diagnosed and treated quite effectively. From your description it sounds like you have a well-known headache syndrome (maybe cluster headache). However, effective diagnosis and treatment aren't possible over the net, so I would suggest seeing a doctor in order to treat it.
