Hi, Tin, and welcome to the forum. Your daughter is fortunate to have a mother who cares so much and is seeking various ways to help her. I'm so sorry to hear she was attacked.
I'm the one mentioned in Luthien's post (thank you for the PM, Luthien!). Short version is, I have PTSD from being bitten by a large dog a little over a year ago. It was my new husband's 100-lb Akita, in our home, a bite to my right/dominant hand...it put a gaping hole between my thumb and forefinger which went almost all the way through, forming a neuroma in the palm, and another inch-long open puncture down to the tendon between my ring and pinky knuckles, as well as some minor lacerations. I'm really lucky in that I don't categorize it as an attack (although it was big, it was a single bite) and I didn't require surgery...so I can only imagine how rough it must be on your daughter. I did require a lot of PT/OT, occasionally have pain and trouble with my hand, and developed a hand disease normally found in Scandinavian men over 50, LOL.
It's good that your daughter is in therapy...I wouldn't have regained any sense of "normalcy" without (although 'normal' has a new definition now). It has been a tough road and a lot of hard work, but the progress is marked over where I was. I still haven't written about it in my diary yet, but I'm getting there.
I'm not sure if there's anything I can do or say to help, but if there is, please let me know...and keep posting, we're glad you're here!
Best,
Mina
