You just had surgery, you're going to be very sore so you need to be patient and also move slowly!
If you want you could take a hammer and hit your thumb as hard as you can, this my take your mind off of your other pain, but I wouldn't recommend this, I find after surgery and I've had 8 of them 3 being major back surgeries and 2 total knee replacements, that meditation with music can help take the mind of the pain!
