I have been dealing with itchy skin since I moved in with my fiance. He lives in an old house but has renovated the majority of it and checked for impurities in the air. I try to put lotion on to help with dry skin and we use a water softener. I do not shower in real hot water so that can be ruled out as well. We have 2 cats and 2 dogs that live in the house, but my cats never made me itch in my previous home, and the dogs no longer sleep on the bed.
However, I seem to itch only while I am in bed. We now use a hypo allergic detergent hoping that would help, but I still sometimes itch while trying to sleep. I have no known allergies and never use to have itchy problems. When we sleep elswhere such as a hotel, sometimes i itch and sometimes i sleep peacefully. I wash the sheets regularly in hot water and the matress is only a year old. It seems that when the sheets are washed, I am ok or a few days but then the itching comes back. Sometimes i itch while not in bed, but not as bad. I have no rash but I do get body acne that comes and goes.
