A contusion (bruise) is an injury to the soft tissue often produced by a blunt force, such as a kick, fall, or blow. The result will be pain, swelling, and discoloration because of bleeding into the tissue. Treatment for contusions includes rest, ice, compression, and elevation (R.I.C.E.).

A hematoma in the leg can cause bruising and swelling. This may occur following an injury, such as a fall or being hit by something. This type of injury can often be treated at home with rest and a cold compress.

One possible cause of delayed hip pain after a fall is a contusion or bruise to the soft tissues surrounding the joint. This could include muscles, tendons, or even nerves that run through the area. In some cases, symptoms may not appear until hours or even days after the initial injury as inflammation and swelling increase.
