Today I had third car angiogram with contrast. First time that evening I deceloped hot flushwd cheeks, the next nite I had hices in my cheeks so dr said rake benedrylnwhich I did and that helped. The secons cat angio was wihout contrast and hospial gece me benedryl and a steriod and the second was fine.m today I had third cat angio and I tokmtwo prednisones last nite and then two more tabs this morning gefore cat angio with vontrast. I had deceloped hiv s on my cheeks so ai called me doctor and he said take two benedryl which I did but now hices are moving up my face. Between my eyebrows. My question is that because I want to go to bed would that be okau? I dont want to hace serious problem when I go to sleep.
