Having headaches above eyes. Sinus xray showed no infection. I have peptic ulcers, diverticulosis and hida scan at 33%. What could it be BP is 137/79?

Not GI-related. Frontal headaches (above you eyes) are not related to any of the conditions you have, ie diverticulosis, peptic ulcers or low gall bladder ejection fraction. Sinus pain, even with normal xrays, is a more likely explanation.
Headaches. May be just plain old headaches, or cluster head aches, vs migraine head aches. May also still be sinusitis and not showing up on x-ray. Consider treating as sinusitis and see if it clears. It may take a full 14-21 days of treatment.
