Before I ever heard about RSD I used word pic's to try to explain to doctors what I was feeling as my pain got worse & worse after corisone injections into my shoulder, etc.
I said it felt like 3 cats had all slid down my arm from shoulder to hand, scratching with all their claws as they went. And, along with the aching in my RT shoulder from the torn rotator cuff, and the feeling like I'd just banged by "funny bone" on my elbow, it also felt like a soldier wearing his boots had just kicked me in the arm pit, causing me to ache under my arm & into my chest.
When told about RSD I looked it up & one of the first things I read was that people with RSD describe their pain with such "vivid" word pictures! Wow!
Guess we can all say we've "been there".
