Can you explain my wrist pain!

[Jimmy242]

I got an X-RAY in October 2016-  findings:  'a remote ununited fracture transeverses the ulna styloid with 6mm bony fragment related to top of the ulna styloid process' - But the doctor said this 6mm bony fragment is too small to be causing pain, so sent for a ultrasound.Here, nothing was discovered, everything appeared normal. There was no cause found for my symptoms: "No evidence of tenosynovitis nor evidence of subcutaneous mass lesion. No evidence of ganglion formation" "Extensor Carpi ulnaris tendon appears intact with the Flexor Carpi ulnaris tendon also appearing normal"

Got sent to Physio who thinks that the bony fragment is actually indeed causing the pain. It is apparently disrupting the ligaments near it and therefore affecting the mechanics of the entire write joint. Now waiting for a fracture clinic appointment for a proper diagnosis! If anyone has any ideas of what exactly is causing my pain, it would be awesome
