Hi
@AnnaE ,
Welcome to the forum.
There's no reason why you shouldn't get a tattoo done. Though I would be wary regarding disturbing it during the healing process? (As part of the aftercare.)
I do have some ink on my upper leg, though I've never injected into it. (More on the side of the thigh.)
Another thought is logging injection sites into an app? I use a freestyle Libre with the Glimp app on my phone as a reader which gives L/R flank or L/R navel in stomach then offers the next site as an option. Same with finger rotation too..
Other logging apps alow the user to take notes which can help.
You may not have a flash sensor, but the free app (no adds.) may help in the interim whilst you decide on the right ink work for you..
I'll tag in
@therower &
@LooperCat to say hello, who I think are inked..
