I have an issue that doesn't happen all the time. First, I do suffer from migraines and I had severe sinus infections due to a syst in my maxilarry sinus cavity that was removed. I don't think those things are related to my skin issue but I don't really know.
What happens for me is if I get an itch and I scratch even mildly, it will leave red swollen puffy and itchy lines on my skin from where I scratched myself. Which in turn causes me to scratch more if I am asleep. I end up waking up and having to go take benadryl because my arms, back, legs will end up covered with these red, itchy, puffy scratch marks.
Sometimes it can take just touching the skin with something, such as putting my arm though a fence to pet my dog. Where my forearm touches the fence it will leave red, puffy, itchy lines. Ends up looking like my forearms have been scratched when all they did was touch the fence.
I was opening a soda bottle with a twist off cap, and my thumb and pointy finger ended up with these type of whelps where I touched the cap.
It seems like some days it happens and some days it don't. For example the soda bottle, I had drank part of the soda and then noticed my finger and thumb itching and looked to see the swelling and puffy areas. Then I had to think back to what I had touched with my finger and thumb to realize thats what it was from. That was the first time that happened. But it seems the same as what happens to my arms or what happens when I sleep or scratch an itch.
I am wondering if this is just a sensative skin issue, an allergy, or a symptom of some other problem. :confused:
