Hey there @krobbersstad, this is very interesting. You have been told that you are not reacting positively to allergens. It is interesting that temperature is a factor for you and if I understood correctly is one that currently is causing your body to react. I also had an outbreak begin today on my right arm. It's been a while since that has happened.

Do you think that stress is a factor? Can you remember being "attacked by the itch" during a time of stress or when there was a decision to be made, or an incident to be tolerated and put to bed? I had a TKR (total knee replacement) in August. From the time I got home from the surgery center up until right now, I have had unbelievable outbreaks and have found that my life has revolved around the itch outbreaks but only on the surgery leg.....not on the non-surgery leg. I am using tacrolimus (the ointment) twice a day to try to keep it under control. So....is that because of some surgical medications that interacted with my itch generating cells? I have an appointment with my dermatologist next week to see what we can figure out.

One final question.....what do you mean when you say that it's Neurological and not allergies? I would appreciate learning more about what you have read.

So I am using the OTC Allegra every day which helps with the arms but this leg is driving me C-R-A-Z-Y.

Let's stay in touch...you have lots of experience which can help others. And that is what Connect is all about.
Thanks for sharing......
