My 10 years old son having swelling in right foot (dorsal swelling). no pain in walking. 3rd right mt foot in xray showing abnormal. ?

How is x ray Abn.?: An "abnormal" x ray could be anything from just reporting the swelling which is already known to a bone, joint or soft tissue problem which may or may not be related to the dorsal swelling. All plain x ray findings are not necessarily serious. Advice about what to do should be only offered after clinical exam and more history. Sorry.
