Hi James,
I didn't see where you made the connection between your blisters and Embrel.
If I recall correctly, the connection was that it appeared at the same time as the other acute allergic reaction symptoms triggered after the Enbrel shot, and he's had a history of bad reactions to meds so it does make sense. Who knows, maybe you're allergic to something obscure that you're occasionally exposed to, and get an allergic reaction too? Either way, at least you've got a solution in the steroid cream, and hopefully James' doc comes up with something useful too...
