Hi Breshea, just ring your rheumy and ask them? I'd say you'rd be ok as long as you monitor for infection. Make sure you go to a reputable piercing place where everthing is sterile. Just keep an eagle eye on the site for any sign of infection.
I've had surgery on these meds and only had to stop humira before it, just missed one dose, talk to your rheumy. I'm sure they will work out a plan for you, golitho
