I never even thought about the chemist in my panic!
Just back from doc my blood pressure fine he did thorough eye check took notes about my brother not that i could tell him much as were not in touch, he said he doesnt think its hrt related and it should heal up in a couple of weeks but to go back if i get another one, he seems to think its just one of them things that happens, im glad i went though as i can stop worrying now, thanks for all your advice xxxx
