I am glad I found this site before I got rid of my puppy. I had the Kenalog shot also back in mid summer of 07. I had a bad case of poison ivy at the time and the shot got rid it. For a month or so I was rash free then I started itching on my head,back and sides. I hate to even brush my hair because it is coming out (thank God I have thick hair). My back still itches and the rash is mainly around my elbows and lower part of my legs. But I will not be wearing shorts this summer unless I can get rid of it. It really looks bad and the itch is almost unbearable sometimes. I have tried several creams and nothing works now I know why. Anyway I thought my puppy was the cause of this until now. I had other side effects but this rash is the worse one and I hope the last.
