Tyson,
I'll keep my post simple. If your neurologist told you that getting a tatoo can be dangerous due to your being immunosuppressed then I wouldn't do it. You've already been through enough as it is. Adding that tatoo may cause you even more health problems.

I know its not what you want to hear but I would hate to hear that you are going through more illness because of the tatoo.

Good luck with your decision.

Shari
