It is now week 4. I was on Prednisone for 10 days. It started on arms, legs, stomach. I have been off prednisone for a week now and it was getting better. As of today, I have a fresh new outbreak on right side of chest and up neck. Why the outbreak again? i washed everything several times. But, i pulled some weeds the other day that were definitely not poison ivy, just grass. I did wash with Techno. The worst part is I went to docs yesterday for followup and all looked good. Then I wake up to it again today. It is very frustrating.
