Wow, that is scary. I haven't tried Eenbrel yet, though they want me to. Are you doing better?
The biologicals are all different, how you react to one, is not necessarily how you will react to another. At least that's what everyone insists.
It seems someone once did have a reaction, but i cannot remember who it was or if it was someone here on HW. I'm sorry I'm not much help.
Let us know what the doctor says - and BTW, welcome to HW!
