Returned from Hilton Sharks Bay on 24th July, by 26th July my son (17) had come out in millions of tiny, angry red spots. On 27th I had them too. Very, very itchy. Doctor thinks it's an allergic reaction to something we picked up by way of tummy bug, we both had the galloping trots but took Antinal and thought we were cured. Has anybody else had similar experience. Samples are at the lab but taking an age to get results!
