Hi , thanks for your question! Just wanted to add that in my personal experience, I've had an inflammation-like pain similar to what you are describing that often correlates/coincides with having an RA flare. It's painful, and I'm sorry you are experiencing this. I'm unsure if it's RA-related, but regardless, if you have any concerns, you should talk to your doctors about this!
Take care,
