Hello. I am having a medium black tribal tattoo removed from my upper arm with Picoway. About 4 weeks after the first treatment, I became very itchy on my forearms, waistband, and legs (everywhere except for where the tattoo is). My doctor diganosed it as contact dermititis, and prescribed predinosone for 5 days. That helped a lot, but after being off it for a week, the itching has come back to my legs and back (not as bad as before). Could this be related to the tattoo removal? Thanks
