How quickly can the symptoms come on and escalate to the need for surgery? I have had itchy hands for several months and then the tingling and numbness started. Now it wakes me up at night. It's only been about 8-10 weeks for the numbness but the surgeon says the tests showed some non responsive areas in one of my hands and I am scheduled for surgery 8/8. Should I wait? The wrist band helps but it comes back when I type and do other things.
It probably has been progressing for some time. What sometimes happens, is that the condition sort of smolders along, just below being clinically apparent. Then, it progresses to a clinically evident stage, and it just seems that it come on and progressed rapidly. But, has actually been going on for some time.
But, it is also possible for the condition to progress quite rapidly. (In traumatic cases, such as with distal radius fractures or crush injuries, it can develop in a matter of hours.)
If you have electrical studies which show that you have significant nerve injury already, you should probably have the carpal ligament released. Nerves do not take injury well, and the condition can become permanent quickly.
If you have concerns about the surgery, discuss them with your surgeon before your surgery.
