Skin infections, also called cellulitis, are caused when bacteria enters a cut, tear, or scrape on your skin. It can occur when your finger or hand is cut or crushed, such as being shut in a door or window.
Signs and symptoms of soft tissue infection include redness, swelling, pain, or draining green or yellow pus. If the infection is not treated it can spread to the rest of the body system and make you ill. Infection can also spread to the bone. Bone infection is called osteomyelitis and can cause bone loss. Bone loss can affect function or cause deformity.
Who May Be Affected?
Anyone at any age can get a soft tissue infection (cellulitis). The skin cut, tear, or scrape might not have been noticed when it happened. It can happen from what seems to be a “clean” injury.
Diagnosis is made by physical exam. There is usually pain. If the redness and swelling are at a finger, then x-ray might be ordered to rule out infection in the bone. MRI or blood work is not usually needed to make the diagnosis. There is often no fever or other symptom.
