Been in search of the full Dave Lum’s Heavy Duty Tattooing. Willing to buy VHS copy or borrow. Talk to a lot of guys about it when I get tattooed and most of them say they’ve seen it but don’t have a copy.
Tend to agree with Hogrider. If it's not painful or oozing then it's probably a watch and wait game. Looks like maybe a thick scab from what I can tell which could just be the result of blood and plasma collecting in that spot during healing. I had this happen with part of my first sleeve resulting in some heavy scabs. Had me worried but it all healed fine in the end. Definitely no harm in asking your artist and would probably give you peace of mind. Sent from my iPhone using Tapatalk
