Years ago I had a small bump on my back. I didn't like the feel or the look, so I requested to remove the small cyst.
It was rather quick, cut out, dig out the cyst stuff, and sell back.
After that my back was in pain. When I lie in bed to sleep it hurt. Painful for few weeks.
Afterwards when it "healed", I looked at the scar and it was unsightly.
It looked terrible and hoped it goes back to normal.
Never did. When I go topless, my back looked like I had a large stab wound that never was stitched.
Learned my lesson not to do any more invasive treatments/surgery (not even Botox, Ugh).
