"Bucky, I’ve been having the recurring nightmares / flashbacks. It’s a little freaky, but it’s a form of PTSD."
Dude, you nipped off a bit of your finger. Not that big of a deal. Easy to say for me maybe since my accident was 8 yrs or so ago and it's well in my past. You'll get through it.
I sympathize since at the time I was going through it, I also had weird dreams and worries of loosing my whole hand. I'm serious. I would wake up at night with my hand throbbing and have some bad thoughts.
Discussions with the doctor about what he was going to do and what I could expect planted some things in my mind that freaked me out. It turns out that thumbs are kind of important for daily life. He was frank - he told me of possible infections, blood poisoning, permanent nerve damage... all different kinds of crap that might go wrong. They were only possibilities but day by day as I looked at the progression of my reconstructed thumb, they started to seem real.
I underwent two surgeries to repair it (table saws don't make a real clean cut) and they weren't sure that they could even save the thumb as a whole. They peeled back the skin like a banana to cut out the damaged tissue and bone then sewed (is that a word?) it back up.
First repair didn't work. All the skin around the stub turned black, dried up and died off, things started turning weird colors. My mind started making **** up... infection... bone infection... nerve damage... Holly crap! I'm gonna lose my hand and it's gonna crawl up my arm to my brain.
He went and did another surgery. He pealed the banana again, nipped back the bone a bit further, cut out more dead tissue and took some fresh skin off the inside elbow of my arm to graft over the end of my thumb. This time the graft took. It was a sucky 10 weeks of surgeries, recovery, arm casts and physical therapy but all worked out A-OK.
When in physical therapy, my therapist gave me an article that just came out (at the time) in one of the medical journals about some dude that had a full hand transplant. His body was growing new nerves into his transplanted hand! The human body is an amazing machine.
Case in point, the skin graft that he took off my arm and put over the end on my thumb worked so well that the hair follicles are still alive. I have whiskers on the end of my stubby thumb. If I didn't work with my hands and wear the hair down, I could probably grow a beard off the end of my lopped off thumb.
Well that's my stubby story.
Goodnight Moon
