If it's on your bucket list, do it. Something small like a bee or ladybird isn't going to cause much hassle in the way of healing. A tattoo is pretty much like a bad graze, and unless you have issues with your peripheries, shouldn't pose a problem if you follow the advice and guidelines of your tattooist.
I have back, arms, wrist and feet tattooed. All were done in the last 10 years, so at least half would have been done with high blood glucose! Especially my feet... which were both done over the last 2 years. I have had no healing problems.
Pain-wise, feet were by far the worst... my left foot has a tattoo that covers the top and goes up the front of my ankle. When it was done my tattooist commented that I was the first person to have it done without flinching, moving, or asking for a break. I told him that it was because I was gritting my teeth so hard that I couldn't speak! Would never repeat that experience.
Contrary to what most people say, my wrists were the least painful but took a longer time to heal (about 2 weeks).
My Mom came with me to watch me get a tattoo once. She claimed that she wanted to check the facilities were safe and clean etc. Mom is a typical, reserved, marks and spencers-wearing 60-something year old. So imagine my shock when I turned around to see her sitting in the chair having an Elvis tattoo done on her shoulder.
She never shows it off, but she doesn't regret it.
