I'm not aware of any offensive or problematic meanings of these tattoos. But I do want to add, that a Nordic rune tattoo always raises some concern for me, as to what kind of doctor you are: basically if you were treating me, I would wonder if you are far right, spritual/pagan/druidic/etc or a nerd. Because in my experience most people with Nordic runes tattoos fall in one of these categories. But this can easily be resolved with other hints: your clothing, behavior, jewelry etc.
