Hello!: Kind of a crazy question, but my cat makes bread (kneads) on my thigh (through my p.j. s ) every morning while I m checking email. This is routine, doesn t hurt and has never left marks. However, from yesterdays breadmaking/kneading episode, which didn t hurt, my thigh is extremely marked up and inflamed. I just had an epidural steroid injection in my lower back (first one) a couple of weeks ago. Could my inflamed leg be a result of a compromised immune system from the shot? Thank you. Carolyn
