Two Weeks Ago I Was Diagnosed With A Possible Retina

Two weeks ago I was diagnosed with a possible retina detachment with hemorrhage. I seen an eye specialist, but he could not tell if it was a retina tear or detachment because of the blood. My question is. I've had a bed headache for the past couple weeks and today when I sipped on a frozen drink it gave me a brain froze with the littles sip of it. I'm very concerned that the littlest sip caused such pain in my head. Another thing I should mention, my eye hurts in the back of it.
