<p>You might also try the non-steroidal Ivarest cream. It’s good against pruritis and appears unexpectedly effective against light biotic infections that can follow the response to intense itch.</p>
<p>Also consider that certain foods may predispose some people to increasing the potential for allergic reaction, and then favorable environmental conditions bring the reaction about.</p>
<p>Thanks for all the good info! Back home now, with only very mild itch and almost no bumps. </p>
<p>Vandy - Interesting link. Although I’ve been in the sun at home in CO (high altitude, with and without sunblock), this happened after my first day of beach exposure. It was probably only 90 minutes, but with intense reflection off the water. So sun reaction could be it. Bummer that sunblock does not help. .</p>
<p>We do this trip every year, so not sure why the reaction this time. Maybe another old age symptom;) The only difference I can think of is that I take a multivitamin and fish oil tablet.</p>
<p>
I get an itchy rash/mild hives on my neck from fish oil tablets. I never liked fish so never ate it; then my doctor suggested I start the tablets and later put me on Lovaza. Many months later, I finally associated the pills with the rash. (I realized that the rash had gone away during a period of time when I wasn’t taking the pills.) It was a delayed reaction; took a couple of weeks to develop, so no immediate association. I gave up on omega-3 supplements. I also finally worked out that lots of almonds every day trigger the rash.</p>
<p>Anyway, considering what PBVS said, maybe the fish oil helped trigger the sun rash. Our bodies are great mysteries, aren’t they!

<p>If it is heat rash you shouldn’t put any kind of lotion on it. When I get heat rash I try to keep it dry, no lotion on the area, and put aloe strait from the plant on it. You can also get aloe vera juice from a health food store and keep it in the fridge. I sometimes use it as a preventative when I know I am going to sweat. I don’t put lotion on the insides of my elbows anymore and I didn’t even get it this summer. Yay!</p>
<p>Look up swimmer’s itch. Microscopic parasites in the water cause it. My son had this one summer. His was all over his chest as well. Time and hydrocortisone took care of it.</p>
