Hello, Thanks for writing to us Every trauma brings a risk of bone fracture (even if the symptoms do not point it) and blood accumulation due to vessels rupture. Such blood accumulation can cause hematoma which sometimes turns into and abscess. After 2 weeks most of mild contusions (except fracture and hematoma) should disappear and no pain should be present after such time. That is why I suggest you to visit your doctor and have and X-ray performed. Soft tissues ultrasound should be also considered in case of no changes in the X-ray. I do hope that you have found something helpful and I will be glad to answer any further query.
