Reinventing The Tattoo Forum

Good evening 

I have run across something after 10+ years of tattooing that I have NEVER seen....and I am hoping someone else in the forum has. I did a tattoo on a client 3 days ago, a large color piece. During the appointment she mentioned she had LYMPH EDEMA on the leg we are working on.....immediate red flag. We finished the piece and I am keeping close tabs with her......and after 3 days the tattoo looks great.....not red...swelling went down as normal and the color is steadfast in there.....except now in 1 spot we are seeing a bubbling ( what appears to be heat rash)....only in the one spot. 

I hav her on aquaphor 2x a day ike I have all my other clients....and it is behaving as I would expect......has any one had expereince healing a lymph edema canvas....or this sort fo development ....I am perplexed and I want to give her the best advice possible...so I figured I would open it up for opnion..the pic is below
