You could be right in that it is “referred pain”. It was explained that the signal goes towards the wrist and when it can’t continue, it will affect the upper arm area. My memory is really bad anymore and I’m afraid I can’t remember exactly what they said. I know they said that this is capable of affecting the strength in my arm and causing me pain there too. I have to admit, this confuses me and I think I need to get a recorder so I can record what is said so I can remember it better! They said that both sides were equal...that the problem was just as bad in both hands and that since the right hand was bothering mme more, I should try to care for that one first. I want to try non surgical options first only because the back surgery has jaded me on surgeries...
I understand what you mean about being jaded.
Good thought about carrying a recorder (I should do that myself), but unless you understand medical terminology, you’d have to do a search for all the terms they use.
Maybe the Mayo Clinic or Johns Hopkins site would be helpful for that. Or look for neuro specialists and see if they have a FAQs page you can search.
Another thought, it might be helpful to search blogs and get it straight from those who have had the procedure done. It might be reassuring anyway.
