Leg pain is very common after a car accident, but it can have many causes. Unfortunately, many crash survivors assume that their pain is “just bumps and bruises” and that it will go away on its own. However, that dull or shooting pain may be a sign of a severe injury, like a herniated disc or a knee or hip injury. Understanding your leg pain’s cause is essential to both your personal injury case and your overall health.

In this post, our experienced personal injury attorneys will discuss common causes of post-accident leg pain and what you can do to minimize it. We’ll also provide tips on how working with a personal injury lawyer can help you secure fair compensation for your injuries.

Common Causes of Leg Pain After an Accident

Leg pain can be up in your hips, down in your feet, or anywhere in between. A crash can easily cause leg, ankle, hip, and knee injuries because our lower body contains many complex joints and supports most of our weight. The following are some of the most common causes of leg pain after a car crash: 

Bruises, Cuts, and Hematomas

A car crash’s trauma can cause lacerations (cuts) and bruises (hematomas) in your legs and other body parts. While a cut will be obvious, deeper bruises may take a few days to fully appear. While most bruises and cuts heal on their own, some require stitches, surgeries, and medication.

If you suffer a deep laceration or develop dark, widespread bruising, see your doctor. These injuries likely need medical attention.

Broken Bones

You have more than 60 bones from your hips to your toes, and any of them can break in a car accident. Bones in the hips, legs, knees, and feet can have small fractures, clean breaks, or be shattered. Any broken bone should be examined by a medical professional.

Serious breaks tend to be obvious due to pain and, in some cases, being visibly misplaced. Tiny hairline fractures are less easily detected, and are sometimes mistaken for soft tissue injuries. However, with time and stress, these small fractures can become more serious.  

Small fractures can often heal on their own as long as the bone isn’t forced to bear too much weight or activity. Large and complicated breaks require more healing time and intervention, perhaps pins, screws, plates, wires, rods, or even joint replacements.

Left untreated, broken bones can lead to chronic pain or cause long-term difficulties with walking and balance.

Soft Tissue Injuries

Injuries involving muscles, tendons, ligaments, and cartilage (sometimes called “soft tissue injuries”) are common in and around the knees, hips, and ankles after a car crash. Symptoms of these injuries can include swelling, a popping sound, pain, weakness, and stiffness.

Sprains and strains, where your muscles and ligaments either stretch or tear, are incredibly common during car and truck crashes. While many of these injuries heal with medication, rest, and time, some require physical therapy and more intensive care. However, sprains and strains aren’t the only soft tissue injuries that you can suffer during a wreck.

Severe injuries to your leg’s ligaments and other structures can lead to surgery and cause long-term problems. If you’re experiencing severe pain and decreased mobility in your leg, your doctor may check you for a variety of soft injuries:

  • Anterior cruciate ligament (ACL) injuries: the ACL stretches between the shinbone and the thigh bone and can be damaged when the knee is impacted. This injury inhibits your ability to twist and pivot your leg.
  • Torn meniscus: the meniscus is knee cartilage that absorbs shock. If it’s torn in a crash, your knee will be very painful and won’t be able to bear weight. This knee injury often requires surgery.
  • Posterior collateral ligament (PCL) injuries: the PCL stretches between the back of the leg and the thigh bone. Like the ACL, it can be damaged with an impact to the knee. This injury tends to be less common and less serious than an ACL injury, but it can still cause significant pain and inhibit movement.

Deep Vein Thrombosis (DVT)

DVT is a blood clot deep within the body. Trauma to the leg, as well as surgery performed to treat that trauma, can cause deep vein thrombosis. In addition to leg pain, you may experience swelling and discoloration that isn’t due to the trauma itself.

If you have any of these unexplained symptoms, talk to a medical professional. Untreated DVT can lead to a pulmonary embolism—a potentially fatal blood clot in the lung. 

Compressed Nerves and Herniated Discs

Sometimes, a car accident’s forces will stretch and pull at the discs in your back. If one of these discs rips or bulges, doctors call it a herniated disc— and it can press on the nerves in your spine, causing a kind of leg pain called radiculopathy or sciatica. Typically, the pain will start in the lower back and shoot down into the leg. You may also experience numbness and weakness in your leg.

You should talk to a doctor to ensure that a serious injury, like a herniated disc,  isn’t causing your shooting leg pain. Medications, injections that reduce swelling, physical therapy, and even surgery may be needed—so don’t delay calling your physician. 


If a bone comes loose from its joint, it’s dislocated. Hips and knees are among the most common bones to become dislocated during a car wreck. While you might not detect a dislocation visually, someone experiencing it will have extreme pain and have a hard time moving the joint.

More than causing pain, dislocations can damage the surrounding tissues. X-rays, MRIs, and other imaging will be able to see the extent of this damage, and treatment might include immobilization, surgery, and rehabilitation.

What Should I Do if I Have Leg Pain After a Crash?

Sometimes, leg pain is a sign of a serious, life-changing injury. You should never ignore your lower extremity pain—especially if you’re also experiencing muscle weakness or bladder or bowel issues. Instead, go to the ER or schedule an appointment with your doctor. Prompt medical care may help you make a fuller and faster recovery.

Next, document your financial and emotional losses. That means you should hold onto evidence that supports your claims, including:

  • Your medical records and discharge slips
  • Crash reports
  • Letters from the insurance companies
  • Pictures you took at the crash scene or of your injuries
  • Medical bills, including bills for any medical devices (like crutches or a wheelchair)
  • Estimates for your vehicle repairs

This information will help your lawyer understand your losses and calculate the full extent of your damages.

Finally, before you speak with the insurance company or start negotiating a settlement, consult with an experienced personal injury lawyer. An attorney can help you avoid mistakes that damage your claims, give you peace of mind, and ensure that you get a fair settlement.
