I went to a neurologist today and he diagnosis me with tension h/a and being just "stressed" but i had h/a since i was a kid, unilateral throbbing h/a and others pain behind my right eye, making it red ?

Resee doc: This is somewhat suggestive of a migraine. You did not mention if the triptans work, or if the headaches gets worse with your period.. Unilateral headaches can be either stress headaches or migraine. The headache that have an occurence with the redness of the eye are more suggestive of a vascular headache. My thought is that you may have a mixed headache type. Resee doc and ask if this is true

Ha and eye pain: What you describe does not sound like tension headaches. Headaches can be very difficult to diagnose in terms of what is causing them and even harder to treat sometimes. Google the local large university hospital in your area and look to see if they have a migraine and headache clinic. Many do. That would be a good place to start. Headaches are a subspecialty in neurology. Good luck
