Hi, thanks for writing to HCM.
After going through the entire description, I also suspect a scaphoid fracture
. In most patients the xrays are negative for a scaphoid fracture as the fracture lines are not visualized clearly in the acute setting.
An xray taken after 10 days of initial injury
will give a correct diagnosis of a fracture as the fracture gap is clearly visible by this time.
So, I suggest you to go for a repeat xray of the injured part and also an MRI
scan to rule out any ligamentous or any other soft tissue
If there is a fracture, the hand is to be immobilized in a plaster cast for 6-8 weeks.
Hope this information is helpful. Good day
