We were all clean no one else has it,  whatever was in my skin just make it go away. it's been 6 months. It's not like 3 or 5 weeks, it just hasn't gone away. I've taken every direction. Friends, dermatologist, vet. It's discolored. it started on her left arm. Patient Went and picked up calamine lotion, my best friend's mother passed away then the following Thursday patient got the vaccine then went to the wake. Within 24 hours patient was fine.
