hello, this issue has been affecting my life constantly for the past couple of months, maybe even years at this point. Whenever i change temperatures, whether that is from a hot to cold or cold to hot environment, my entire body gets INCREDIBLY itchy and painful, as if i'm being pricked across my entire body. For example: I walk out of my room, downstairs to get a drink, walk back into my room and all of a sudden my entire body is incredibly itchy and painful. The main areas are my chest, back, neck and head. it is bothering me on a day to day basis and it's becoming a huge nuisance in my life, please please please do help me if you can!
just to add, this isn't all the time. Some weeks when this happens i won't have any issues with itching or pain, but other weeks it may be constant and awful. they can last for 10 seconds or 10 minutes. This also happens if i get worried or anxious.
