So sorry to hear this. I went through it 14 years ago am still kicking. You will be amazed at what great therapy dog training is for you. It got me through so pretty tough patches. Your left hand back will come fine with the training you do. The dr. thought I would never be able to hold my right arm up straight but as I said before Bill's nagging and my determination made it possible. Take care, be aggressive and my thought are with you. It's a bummer.
