Hi there. The skin in that area is quite thin and delicate, and that tattoo is in there.
There isn't really much to be done unfortunately. You could try to find a skilled artist to re-outline it in white, but that will not likely accomplish much for you. A shadow in white will just make the whole thing seem bigger still.
I recommend you just accept the tattoo as a reminder for where you were in life at the moment you got it, and move on to the next one.
Next week is the Moncton Hub City con and it turns out John Gray (@sourjohn) is going with Sailor Jerry Swallow. Super stoked.
Going to get him to put this rad Spaulding geisha in my forarm, a diamond girl on my bicep, and hopefully this german skull guy on my arm somewhere. (off his coworker Dave's sheet)
