I've been using pascalite clay poultice on my legs for awhile and everytime I take the clay off my legs are red and itchy and it takes a week or more to go away. Can anyone tell me why this happens and how to get red of the itch sooner? I had been having pain, tingling and numbness in my legs for a few years before I found out about the clay. I use it on my face and throat - over my thyroid and I don't have the same reaction.
