I mistakingly thought I could take day 4 off from treatments. This is not day 4 in my overall treatment since diagnosis - just day 4 with using the mustard paste in various products. My results were so dramatic with the dry mustard, I thought I was okay for a day or two. And I was fine until about 10pm. Then, the terrible itching started again, and on areas of my body not previously itchy (legs, lower arms), so I applied the dry mustard paste with a mix of permethrin and Eurax. It seemed to work.
