Not a doctor, but I would be worried if there are other similar symptoms elsewhere in the body, or if your injured wrist had an sudden/forceful injury recently (eg falling down and breaking your wrist type, not a gradual buildup/repetitive injury). Chronic damage/injury is definitely a concern but it won't get worse by itself without something else. But going to the GP/family doctor isn't a bad idea at all.

Right, that's why I was only ready to believe it after the doctor did the battery of tests. The checks were very thorough: nerves, vascular system, blood tests, etc. They took a week, and I received diagnoses from doctors of two specialties which were reviewed together.
