question about dealing with a scarred tattoo

i have a 6 yr old tattoo that i absolutely hate, it was done kinda poorly and i'm pretty sure most of has scarred. what are my options? i know people get tattoos over other scars all the time but i don't know how it being raised still (not keloid level raised but still extremely noticeable to the touch) changes how or if a coverup can be done. apologies if this is the wrong place to post this.
