It sounds like you may have a serious problem get a cat scan to determine the problem if it persist.
I don't think that is diabetes or symptoms of diabetes. The symptoms of diabetes are:
Frequent urination
Excessive thirst
Extreme hunger
Unusual weight loss
Increased fatigue
Irritability
Blurry vision
Maybe you should go to a neurologist, a doctor who deals with things involving your head/brain. Or maybe an ear, nose and throat doctor, maybe it has something to do with your sinuses or some other thing with your nasal cavity, since it is so close to the eyes.
