Vexing Aspect of My Heart Attack

While I felt no pain during the heart attack and my doctor told me there is no residual damage to my heart, I do have a vexing problem. The connection between my fingers and my brain has been rewired. Typing is not working well. I keep getting letters inversed, or one hand or the other shifts one key over, making a complete mess. The good news is I have a lot of typing to do, so perhaps practice will correct this with time. The guitar is even worse. I know which string and fret I want my left hand to press, but my left hand can't find it! Very vexing and I am working overtime to get that sorted out. I have less than 2 months to the next concert on March 24th. I am doing all I can do, which is to diligently work out these problems. Vexing, it is!
