The last few weeks when I have been outside in the sun my arms have got really itchy and got like prickly heat on them,. When I was out yesterday in a particularly sunny place, within minutes I was itching and then blister type things appeared all over my arms. It was so itchy that I had to go home and take antihistamine. It sstarted itching again in the early hours of the morning and is now driving me nuts again. Does anyone else get this and how do you avoid it?
Thanks
