my foot is swollen only at the front of the foot not at the ankle. it is now very painful difficulty walking?
if you were standing in your feet for long periods recently (the most possible ) then you need to see an orthopedic doctor and getting a foot xray. it may be stress fracture in your metatarsals. a mild case but needs treatment. other possibilities as increased uruc acid levels and plantar fascitis please let me know other history if this is not your case.
