Hello and Welcome to Neurotalk Support Groups,
I am so sorry to hear about your wrist. What a way to end your vacation! It is good that you were able to get home for your surgery.
I think pursuing an EMG or nerve conduction study is a sound idea. Nerves are easily compromised and while even just swelling can cause problems for nerves there are inherent risks of injury or entrapment from surgical procedures and hardware. The testing will give you useful information and an important rule out. Hopefully, they are just "knocked out" a little from the procedure and will wake in time.
We don't have an area specific to orthopedic procedures but you will find conditions not listed with a specific board here.

Peripheral Neuropathy
The Search feature at the top of every page will help you look for specific topics and FAQ will answer general forum usage questions.
Please share any other concerning or unusual symptoms besides the tingling and contraction with your doctor. Swelling beyond the normal post-op expectation, temperature or color changes, muscle tremors, atrophy, etc. These can indicate nerve entrapment or other syndromes and will have an impact on your treatment needs.
Keep up the therapy. Gains can be made over time and the body has an amazing capacity for healing. There is hope even for challenging cases as I can personally attest having had a nerve injury and complicated repair. I hope answers and improvement come your way soon.
