Have you had an updated MRI/Xray/ultrasound of your wrist after your surgery earlier this year? Have you had cortisone injections in your wrist? Are you wearing splints/wrist braces to help with your healing and when you sleep (so you don’t injure your hand/wrist when moving in bed)? Did you do physical therapy after your recent wrist surgery?

I had carpal tunnel surgery a couple months ago and wonder if you had the twisting TFCC tear occur since you didn’t have your cut ligament limit your movement when repetitively changing diapers (more range of motion in your wrist).

I use Voltaren gel for inflammation/pain in my wrist and still wear my wrist braces so I don’t injure my wrists when I sleep (my wrists/arms are weak due to other health issues, too). You may also want to try Salonpas lidocaine pain patches on your wrist to see if it can help calm nerve pain.
