Hi sailgirl and welcome to the Allergy Forum on HealingWell!!
I personally would never have thought that 60 degrees is cold, so my first thought would be that the temp. of 60 degrees alone may not be your problem. That, of course, is just my guess and I am not a Doctor. Does this happen when you are outside all the time? I've heard of 2 things weather-wise in allergy reactions.
One is from hypothermic temperatures, especially when swimming in the cold water, but it is fairly rare.
The second is an allergy to the sun, which does also affect some people.
My suggestion would be to definitely sit down and discuss this with your Dr.!~and see what he/or she thinks.
Let me know what happens! Teri
