Motor vehicle accidents can cause more than just cuts and broken bones. Oftentimes, the force of a collision leads to injuries beneath the skin that are not immediately visible.
These deep tissue injuries can damage muscles, ligaments and other soft structures, sometimes with long-lasting effects. Recognizing these injuries early is vital in helping to ensure proper treatment and recovery.
1. Whiplash and cervical strain
Whiplash is one of the most common deep tissue injuries after a car crash, particularly in rear-end collisions. While some people feel pain immediately, others may not notice symptoms for hours or even days. Treatment often involves rest, gentle stretching, physical therapy and pain management. Early diagnosis is critical in helping to ensure long-term mobility and preventing chronic pain.
2. Muscle contusions and hematomas
The force of impact during an accident can cause blunt trauma to muscles, leading to contusions or hematomas. These injuries happen when blood vessels under the skin rupture, causing pain, swelling and discoloration. Deep muscle bruising can significantly limit movement and may take weeks to heal. In severe cases, a hematoma may require drainage to relieve pressure. Applying ice, resting the affected area and following a physiotherapy program can aid recovery.
3. Ligament sprains and tendon injuries
Ligaments and tendons are critical connective tissues that help stabilize joints and support movement. In high-impact crashes, these tissues can stretch or tear, particularly around the knees, shoulders and ankles. Sprains and tendon damage often require a combination of immobilization, targeted exercise and in some cases, surgery. Delayed treatment can lead to joint weakness and recurring injuries.
Deep tissue injuries from motor vehicle accidents are often underestimated because they are not always visible immediately after an incident. Being aware of these injuries can help accident survivors take appropriate medical and legal action as soon as an accident occurs.
