I agree with all here, it's imperative that you see your doctor again. Maybe you can print out your initial post and then add things to it and bring it in so the doctor can read it. Sometimes talking to dr's can feel intimidating and we then "forget" something we thought was important to talk about. Been there, done that...hate when it happens!
I'm very concerned about you. I'm concerned that you may at some point have a physical injury that you may not be aware of if your not feeling pain properly or that maybe the pain manifests as something else or somewhere else other than where the injury is.
I'm sorry you are going through this and I hope you can find the strength to get back to the doctor very soon and get some testing done. Wishing you well!
