Lump on skin after popping spot - tattoo in 2 weeks!!

Hello. I went camping about a week ago. I came back to find a nice big spot on my back - the type with a big white head on the top, waiting to be popped. It was really painful to lay on, so o went ahead and popped while keeping everything as sterile as possible. I squeezed until the white was gone, and only blood came out. I then cleaned it, put some sudocrem on it and left it. After about an hour, I wiped away the sudocrem and the blood and pus which was oozing out. I then put on a thin layer of sudocrem, a plaster on the wound, and went to sleep. A few days later, skin has formed over the area. However, there's now a lump which has a red area (sort of like a red spot under the skin). Is this just healing? I have a back tattoo in two weeks, and I'm really worried. What should I do?!

Now that i re-read it. I think it's best if you just cancel the appointment for the sake of any unnecessary pain you'll receive due to that spot.

Maybe your first port of call should be getting this lump checked out?
