Yes, I would be careful!

Maybe look up on Google to see if you can find any info or research, other people going thru the same thing.

I have no tatoo's but I have noticed over the last 4 or 5 years with AS that things I could normally do like I have my ears pierced twice.

My daughter and I decided to get our upper ear pierced (I had mine done before actually did it myself) but this time (proffesionally) she still has hers and I had to let mine grow back it hurt too much and stayed infected even with like sterling silver.

Also have had my nose pierced 2 times (the little cute tiny stud in the side) did them both myself first time no problem after time took it out and it grew back the next time same thing would not quit hurting, stayed infected.

So I have noticed over time my body able to handle less (intrusion) so it looks like my days of additional piercings or a tat might be over.

Good luck!
