If it was your eye drops I would expect it to be both eyes. Plus its an uncommon side effect of the drops. Plus dry eyes are more prone to cause the eye to feel dry, irritable, sandy, like wind was blowing on them and not a deep pain.

Dr it is not the headaches it is the eye pain that I am stuggling with. Do the eye drops cause dry eye which can cause the eye pain?
Optho knows I take BP medicine and says it is unlikely the cause.
Suggest you call your ophthalmologist with this additional information. Neither Xalatan nor Travatan Z cause headaches in all but the most rare cases
It may not be your eye (other possibilities sinus, blood pressure, tension, migraine)

I am also taking BP medication Bystolic so not sure if that has anything to do at all. Thanks
