<s>[INST] I have had a painful wrist for about 6 weeks now. It s Painful when I put my thumb up. It is tender and slightly swollen on the bone that sits at the thumb side where it joins the wrist. I fell around the 6/7 weeks ago but it was my ankle that was swollen so I did not pay attention to my wrist, then when it did start to hurt I didnt connect it to the fall and thought it may be some kind of tendonitis. I told doctor and she s sent me for X-ray when I told her I had fallen a while ago. The X-ray came back normal, but it still hurts and at times when moved certain ways it makes me stop dead for a second or two with the pain. Do you have any ideas what it could be. Many thanks. [/INST] do a CT scan. little carpal bones fractures often cannot be seen in basic xray projections. a scaphoid/trapezius fracture should be easily excluded by this. if the CT is negative, a RMN os useful to analyse ligament injuries </s>
