Hi there!
Well, it would be difficult to comment on the situation without knowing the relevant clinical details such as the type, location and severity of the injury etc. A bruise is likely to heal itself in a few days, while a clinical evaluation by a doctor would be required to rule out other injuries and for appropriate management. I would suggest consulting an orthopedician for the same.
Hope this helps.
Take care!
Can anyone answer my request for information on the above comment??
