I feel your pain. I took my dog for pee outside. While he was running around in the back yard, I went to sit on a long patio chair. As I sat down, the leg support didn't feel right. So, I leaned over and put my hand down to brace myself so I could look under the chair. As I shifted my weight, the chair collapsed and my finger got caught in a metal bracket. If felt like I hit it really, really hard with a hammer.
So, I started shaking my hand because it hurt. After about the 3rd or so shake, I noticed a lot of blood hitting my face. I looked down and it was raw hamburger and a bone was sticking out. mmmm.
Went to the hospital to get stitched up. Found out that I was actually missing a part of my fingertip. It had apparently got stuck in the bracket, and it pulled off the skin, and with it the nail.... because they couldn't put the tip pack on, they just cut the bone down. It sounded similar to cutting your toe nails. I wanted as much length as I could spare, so they didn't fully close the wound, and it took about 4 weeks longer to heal. Thankfully, and I really do mean thankfully, the nail grew back (doc's said it wouldn't). I lost a few mm from my right middle finger, but because the nail is there, you can't tell unless you know or really examine my hands.
It didn't hurt once I got to the hospital and I didn't take any meds that day, and only had the local anesthetic in my finger when they fixed me up... but by god when that freezing wore off, that was something else. I was in agony for a good night or two. Then, it just got better, but doing regular things like closing a car door or banging it in the night was excruciating pain... not to mention that when the skin was healing, the gauze always stuck to my skin trying to regrow. So, every night, I'd have to soak my hand in warm water and pry the gauze off my mangled finger.
I was back playing hockey in I think 3-4 weeks
But, playing guitar, typing or even just opening a box is still an issue I'm trying to get used to... even picking up chip crumbs... can't do it... always falls out... haha.
Thats my story.
