My husband is experiencing continual headache and I recently noticed that his pupils are often unequal in size. He also has the following symptons = Mood swings/depression  sleep problems  not eating properly  not interacting with friends and family unable to make decisions
His understand your concern. Headache with change in pupil size require neurologist work up. Fundus examination / CT scan will be useful. Mood swings can be part of stress and depression. If you have blurring of vision and dizziness then go for neurological examination. Routine blood test and examination are also advisable. Consult neurologist and get help. Glad to hear from you. Thank you.
