I have it too. I first had it 17 years ago when I was pregnant with my daughter and in Beauty school. My dermatologist told me to quit or it would never heal. It was awful. My palms were both covered in blisters and peeling. I quit working as a cosmetologist a year later and eventually they healed up and stayed pretty good until three years ago. I got into a car wreck and they have been inflamed ever since. Its a real pain.
But here is a strange discovery: two weeks ago I broke a molar and was taking Ibuprofen three times a day. All my blisters cleared up, but now I have a rash on the back of my hands.
I wish I had some answers for you.
I wear gloves whenever I cook or clean just to keep from making it worse.
