Muscle pulls

Many grapplers are unaware of the risks that come with participating in jiu jitsu. Though it is an incredible sport, it can prove dangerous if one does not take the necessary precautions. One such precaution is stretching before and after class to prevent muscle pulls. With constant movements in all directions, wrestlers tend to forget how important it is to stretch their muscles to avoid injury.
Injuries to muscles are common in jiu jitsu due to the frequency of skilled grapplers' use of top-of-the-body locks, joint locks, and general brutish wrestling. Though comparatively low in incidence when compared to other high-performance sports, these injuries can be a major problem for athletes who have to compete with sore or strained muscles.

Rib fractures

Rib fractures are one of the most serious injuries that can arise from jiu jitsu, and they can happen without any contact to the ribs. They usually happen due to a strain on the rib cartilage, but some people might not experience any pain until a few days after the injury. A buildup of pressure in your chest is a sign that you have a rib fracture. If you have this type of injury, it's important that you see a doctor as soon as possible. 

Head injuries

Few sports are as fundamentally fit for the competition as Jiu Jitsu. The training is challenging, the competitions are tough but fair. One of the most frequent injuries in BJJ is head trauma. Matched up against their training partners, athletes often collide with each other's heads; this can lead to concussions and bleeding near the skull. Almost all practitioners have experienced some form of concussion at one point or another.
While it's rare for a jiu jitsu competitor to suffer an injury that causes them to miss competitions, concussions are often the most common type of head injury. In fact, some studies have shown that as many as 10% of all athletes participating in contact sports have suffered from concussions. In Jiu Jitsu, head injuries can be caused by both direct and indirect contact with another person or object.

Knee injuries

Knee injuries are an unfortunate reality of competitive jiu jitsu. Many factors can lead to injury, but the most common is overuse. This article will discuss how to prevent knee injuries in jiu jitsu and what steps to take if one occurs.
There are many ways to prevent knee injuries in the game of jiu-jitsu, but the most important thing for beginners is to master basic techniques first before moving on.
Injuries to the knee in Brazilian Jiu-Jitsu (BJJ) are a significant concern for both athletes and coaches. The most common injuries are to the Meniscus, ACL, MCL, and Posterior Cruciate Ligament (PCL). Preventative options include wearing a knee brace or sleeve, icing after training, and strengthening the Quadriceps.

Herniated discs 

Herniated discs are a common injury in the martial arts world, but it can be anything from an annoying nuisance to a debilitating condition that forces the individual to give up their sport. The injuries normally occur when a person is being choked from behind and they have been doing this for quite some time. When the nerve roots are compressed too much, they become irritated and sore. This will cause it to bulge out of the disc and irritate the nerve root canal.
Injuries in grappling sports are unfortunately too common, and one of the most common injuries is a herniated disc. What should you do if you injure your neck playing jiu jitsu? The answer depends on where and how severely you're injured (and other factors like age and lifestyle). There's no single "right" treatment for all herniated discs, but consulting with a doctor or physical therapist can help evaluate your options.

Biceps tendon tears

Some people may have never heard of the term "biceps tendon tear," but many professional athletes are familiar with this common injury that can sideline an athlete for weeks or months. If you are a long-time practitioner of Brazilian Jiu Jitsu, then you know that to get to black belt level it takes hardcore dedication. It also means putting your body through intense physical strain every day.
The biceps tendon is one of the most important ligaments in our body. It attaches at the shoulder joint and helps the arm move up and down. The biceps tendon can tear due to sudden movements, injury, or due to an overuse of the muscle. Tears are very similar to a hamstring rupture because it's common for the athlete not to feel any pain until they experience a "pop" or "snap" sound, followed by excruciating pain.
