<human>: Hello, I was injured two months ago in a military training school.  All of a sudden, I notice a large lump growing fast on top of my left wrist, with the pain getting worse each day.  Should I have it checked out immediately or wait to get an appointment?
<bot>: Welcome to Chat Doctor .1. You can wait for an appointment, only if the pain is in limits.2. It can be a ganglia (cystic lumpy areas) or bony out growth.3. In your case if you are my patient I would have asked for the ultrasound of the lesion to see the extension in involvement of adjacent anatomical areas, and an AP/LAT of left hand and wrist to rule out the bony causes. 4. Afther that to plan weather to excise the lump - act accordingly. Anything to ask ? Do not hesitate. Thank you.
