Whether it’s from a wild pitch, a runaway puck or a lineman’s shoulder, a big hit to your thighs can stop you cold. The good news is that your bones have escaped intact. The bad news is that you now have a massive and painful welt that may stick around for a while.

A quadriceps contusion, otherwise known as a thigh bruise, is a common sports injury. However, since most sports require constant and nimble leg movements, the pain of a thigh bruise can make it difficult to get back into the action. Fortunately, with the right treatment and recovery pace, you can be back on your feet relatively soon.

Below, we’ll discuss what happens when you get a thigh bruise and why it looks and feels so intense. We’ll also show you what you can do to recover at home and when you might need to get help from a doctor.

What is a quadriceps contusion?

Your quadriceps, or quads, is a group of four leg muscles that sit between your waist and knees. Together, they straighten your knee and play a big role in how the lower half of your body moves. And since they’re one of your body’s largest masses of muscle, there’s plenty of surface area that can get hit from the outside.

A quadricep contusion is a muscle bruise. Unlike a skin bruise where blood vessels are broken only under your skin, a muscle bruise happens when an impact damages the fibers and connective tissue of your muscle while leaving your skin intact.

What can cause a thigh bruise

A quadriceps contusion doesn’t happen on its own. It requires a significant amount of outside force to hit your thighs in a way that causes a muscle bruise. That’s why athletes in competitive and high-impact sports are prime candidates for thigh bruises. Anytime there are flying objects (such as baseballs, hockey pucks or tennis balls) or hard-charging body parts (like in football, hockey or soccer), a thigh bruise can happen.

Symptoms of a thigh bruise

Let’s say you get hit with a hockey puck, launched with a slapshot directly into your thigh. The first thing you’ll feel is pain – lots and lots of pain. Your skin and muscles just took a massive blow that caused damage. Fortunately, your muscles cushioned the blow and protected your thigh bone from getting fractured.

However, the force your quads absorbed is now causing the site of the injury to start swelling. Soon, you’ll start seeing the skin at the place of impact turn red as the microtears in your muscles start to bleed, causing the telltale red splotch of a bruise. After a few hours, these colors will start to turn dark blue and purple.

What to do if you get a thigh bruise

The first thing to do with a fresh contusion is to ice it right away. Applying ice in a clean towel will help protect the injury and reduce swelling. Next, check out the damage. Fortunately, most thigh bruises won’t require immediate attention from a doctor. But if the bruise is very large or very painful, TRIA’s orthopedic urgent care locations can help right away.

Diagnosing quadriceps contusion severity

If you need to see a sports medicine doctor for your thigh bruise, they can take a detailed look at your injury to see how severe it is based on the amount of pain you’re feeling, loss of function, swelling and bruising. They can also check to make sure that your underlying bones are fine, swelling is under control and blood is flowing freely.

There are rare cases of thigh bruise swelling cutting off the flow of blood, causing damage to surrounding muscles and nerves. Called compartment syndrome, this serious condition requires immediate medical attention, including possible surgery. Go to the emergency room right away if the pain from your bruise becomes worse or if your bruise starts to feel numb or warm, or your leg becomes weak.

A thigh bruise will take time to heal – fortunately, most do within a few weeks. In the meantime, RICE will be your key to feeling better:

• Rest – Give your leg plenty of downtime to recover and heal. Limit your activity and possible stress on the affected area.
• Ice – Keep the bruise iced for 10-20 minutes at a time, three or more times a day. Even better, keep your knee slightly bent while using ice to reduce pain and inflammation.
• Compression – Wrapping your bruised thigh with an elastic bandage can help keep swelling under control while providing support.
• Elevation – Propping your leg up on a pillow while keeping your knee slightly bent can also help with healing.

For pain, acetaminophen (Tylenol) can help. Just make sure to follow all label instructions, especially when it comes to taking the right amount.

Also, avoid heat within the first 48 hours after getting injured – hot showers, hot tubs and hot packs can make swelling worse. Avoiding alcohol during the first two days can also decrease the risk of additional swelling.

Once you’re ready to start moving again, take it slow and steady. Begin with a gentle range of motion and exercise your quads lightly to slowly build strength and flexibility. And when you’re back on the field, court or rink, a little extra padding for the recovering area can help keep you protected in case another unexpected ball, puck or shoulder heads your way.
