BTDT, I had my median nerve severed and repaired. I was in a hard cast for 10 days and then in a soft cast for 6 weeks and had limited use of the hand while I was in PT. Stick to your PT, it hurts, but you will heal if you follow their instructions.
Socks are a pain in the ass for the one handed. You need someone to help or it takes much longer to dress. All dressing is a PITA, you will find what clothes work best for your particular situation. I lounged around in a lot of tank tops and shorts with elastic waist bands. I had my surgery in the summer, so footwear was flip-flops. Slip on shoes are indispensable…
Plan ahead for the bathroom. Don’t wait until you have to go. Even pants with a waist-band are hard when you are trying to do things one-handed, being a man, you might have a “different” experience. Get your TP all arranged before hand and maybe get some wipes. If you are taking a med that constipates you, take a stool softener with each dose, really helped for me. (Sorry, TMI)
Showering/bathing-Husband would put face soap on one wash cloth and body soap on another. He would put the shampoo on my head and help lather. I would rinse and he would then put the conditioner on my head and I would rinse. After that, I was ok with the two washcloths and I could finish my shower. Maybe get an electric shaver if you want to shave.
Any containers with sealed lids were tough. I made sure lids were loose so I could open one-handed while husband was at work. Paper plates and disposable cutlery was a big help, I couldn’t wash anything. Incidentally, we were having our kitchen remodeled when I hurt my wrist, so I wasn’t cooking anyway. When the kitchen was back to normal, I wasn’t so we still did a lot of take out. I gave husband a list of things to do before he left for work so I could make it through the day. He would open cans and put it into tupperware so I could access things much easier.
I learned to do a lot of things with my non-dominant hand. I learned how to mouse left-handed and just typed one-handed until I felt well enough to use both hands.
What I wasn’t prepared for was how tired I was after the surgery. I did sleep a lot and I guess that was the healing process. I did end up sleeping in the spare bedroom. It was much easier considering my sleep schedule was “off” and I napped a lot. I would get up in the middle of the night for snacks and pain meds, so I didn’t disturb my husband. Plus, I didn’t have to worry about husband moving around and disturbing me. The sleep will happen, you will instinctively not roll onto the hurt area.
