In age order;
Age 11 months - I had major heart surgery and have a big scar around the left side of my chest from under my left breast to almost the middle of my back (but following under the line of my shoulder blade). This was back in the day when they cut around rather than down for heart surgery). Funnily I don't mind that scar. The one I do mind is the one in my left side which is about an inch long, but hasn't stretched as I've grown. I've always been able to put my finger tip in it.
Age 6 - I have a small oval one on my right cheekbone where a dog bit my face and its incisor tooth pierced my skin (got off v. lightly as could have been much worse).
Age 9 - I was climbing on an old, rusty, iron bar, shaped like a hurdle but with a flat top about 3" wide. I was walking along it one foot in front of the other when I slipped. I hobbled screaming into the house where my mum whipped my jeans off to look at what I'd done. There wasn't a mark on my jeans, but when she pulled the left leg down my inner thigh spilled out. The material had been holding it in place. Makes me shudder remembering it.
Age 10 - I was cutting white material with a pair of very sharp material scissors. I didn't realise anything was wrong until the material turned red. I cut the tip of my finger off. It couldn't be sewn back on because i'd cut through the flesh diagonally along my finger. My mum grabbed my hand and thrust my finger into a bottle of TCP (you could have peeled me off the ceiling!) To look now you wouldn't even know.
Age 16/17 - sounds ridiculous but I was waitressing when someone knocked into me. I was carrying 4 plates and one of them had courgettes on which were fresh out of a pan of boiling water. One landed on my inner wrist, and because I couldn't get it off straight away as I had my hands full, it stuck to my skin. I've been left with a small round scar that when I get hot and my skin goes pink shows up white.
Age 17 - got caught up in the mosh pit at my first proper gig and ended up having 6 stitches in my head. It's under my hair, but you can definitely feel it.
Age 22 - I pulled a file off a metal filing cabinet and the whole tray fell off. I tried to catch it and it hit the top of my middle finger by my knuckle. It almost cut to the bone, and has left a scar, although is only a silver line across the top of my finger.
Age 31 2 - I had an allergic reaction to a med I was on and had to have a biopsy of the skin on my arm. They used what looked like a mini apple corer and took a cm deep sample. They closed it with 1 stitch but it has left a round scar with a single stitch mark through it
Between ages 34 and now (42) - I'm a wheelchair user and have little feeling in my legs, and I fell asleep with my feet on a hot water bottle. It had a cover on and didn't leak, but because I can't turn my legs in bed I slept like that for 8 hours. According to the hospital I basically slowly cooked my feet. I had huge burns on my heels, which have left pink shiny scars on both feet.
I was using a massage type cushion on my legs to help with circulation (the type that have rotating metal balls inside), and instead of the recommended 20 mins, I fell asleep and it was on for about 90 minutes. I ended up with quite bad friction burns on both calves which have scarred.
I was ironing (have an adjustable height ironing board), and I pressed the steam button totally not thinking about the fact that my legs were under the ironing board. It went straight through and scalded the top of my knee.
I'm really not very lucky with burn type injuries.
