I had surgery on both of my thumbs about 20 years ago. Right thumb first along with carpal tunnel fix and left thumb six weeks later. I had help at home but really managed well on my own. I remember that I needed to keep it elevated for a while, and wrapped, but things might have changed since then. Both surgeries were incredibly successful and I’m so grateful to have had them. I have not had trouble again. It did not change my penmanship once they were healed. I didn’t have PT. Good luck and healthy healing.
