Hi I began breaking out in hives when laying on my couch. I never had problems before until we moved into a new house. We decided to move back into our old place and took the couch with us. I still break out in hives when i lay on it and now anything that comes into contact with the couch makes me break out in hives. Blankets and pillows especially. I got rid of the couch but the problem is still there. What do you think it could be?
