My tattoo has had a weird rash for over 6 months I ve been to the doctor over 5 time they keep miss diagnosing it I take what s prescribed and it got a tiny bit better but just goes back and gets bigger it s only on the tattoo I got it almost 7 years ago.I got it while I was in prison. My girlfriend and I looked online and found a condition that I cant remember what it s called but there was 2 that we thought it could be one where your cells think the tattoo is something bad and they go to fight it and the other is something that usually people with dark skin pigment get I can send a picture of my tattoo but it s very painful and looks horrible it s on my shoulder and the emergency room and several doctors can t obviously figure out the rite diagnosis so I need some help
