"Little League elbow" is a common name for an overuse injury to the growth plate on the inner side of a young thrower's elbow, caused by the repeated stress of throwing. It usually shows up as pain on the inside of the elbow, sometimes with swelling or a loss of range, and it tends to get worse with throwing. The big drivers are too much throwing without enough rest, year-round play, and breaking balls too young. This article explains the term in plain English, but it is not a diagnosis. Only a doctor can diagnose it. If a young pitcher has elbow pain, the answer is to stop throwing and see a doctor, not to push through.
If your kid pitches and his elbow starts barking, "Little League elbow" is probably one of the first things you'll type into a search bar. It sounds scary, and the flood of medical language out there doesn't help. So here's the calm, plain-English version of what the term means, what raises the risk, and what to actually do. One thing up front, and we'll say it more than once: this is general information, not a diagnosis, and elbow pain in a young pitcher always means stop and see a doctor.
What the term actually means
A young pitcher's bones are still growing, and growth happens at soft areas called growth plates. There's one on the inner side of the elbow, right where the muscles that flex the wrist and forearm attach, and right where throwing puts the most stress. "Little League elbow" is the everyday name for irritation or injury to that growth plate from the repeated pulling of throwing, over and over, before the area is done growing. It most often affects pitchers roughly in the 8-to-15 range, while that growth plate is still open. The medical world has a longer name for it, but the idea is simple: it's an overuse injury to a still-growing part of the elbow.
“It's the growing part of the elbow, doing the most stressful job in the game, too many times.”
That's why it's an overuse problem, and why rest is the center of the answer.The warning signs
Here's the part that matters most for a parent: knowing the difference between normal, temporary soreness and a signal to stop. Ordinary muscle soreness after an outing is common. Pain that lives on the inner elbow, sticks around, or changes how he throws is a different story.
| Normal-ish | Stop and see a doctor |
|---|---|
| General arm tiredness that fades with rest | Pain specifically on the inside of the elbow |
| Mild, all-over soreness a day after pitching | Pain that doesn't go away with rest |
| Feels fine and throws normally after recovery | Swelling, or a loss of full range of motion |
| No change in how he throws | Changing his motion to avoid the pain, or trouble straightening the arm |
If anything in the right-hand column shows up, the move is simple: he stops throwing and gets seen by a doctor. Pitching through elbow pain is how a manageable problem becomes a serious one. This is the same line we draw in our guide on arm soreness after pitching: soreness can be normal, but pain is a message.
What raises the risk
Little League elbow is an overuse injury, which is actually good news, because overuse is something families can influence. The biggest risk factors are well understood, and most of them come down to volume and recovery.
Too much throwing, too little rest
High pitch counts, not enough rest days, and pitching while already tired all pile stress on that growth plate. Rest is when the arm recovers.
Year-round throwing
Never taking months off from throwing gives the arm no chance to recover across a year. Time away from the mound is protective, not lazy.
Breaking balls too young
Curveballs and sliders add stress to a young elbow. Waiting on them, and getting fastball command first, lowers the load.
Following sensible pitch-count and rest guidelines is one of the most protective things a family can do, our guide on pitch counts by age lays out the daily maximums and rest days. None of this guarantees a healthy elbow, nothing does, but it meaningfully reduces the risk, which is the honest goal.
What to do about it
If you suspect Little League elbow, the path is straightforward, and it starts and ends with a doctor. Stop throwing. Get it evaluated by a physician or a sports-medicine professional who can actually examine the elbow and, if needed, image it. Recovery for overuse conditions like this usually centers on rest from throwing, sometimes for weeks, followed by a gradual, guided return under medical and coaching supervision. The one thing not to do is to keep pitching and hope it goes away. It won't, and the elbow is not the place to gamble.
This is also different from, though related to, the shoulder version of the same growth-plate story, our guide on why a young pitcher's shoulder hurts covers that one. Both share the same lesson: a growing arm has soft spots, and pain in them is a stop sign.
The bottom line
Little League elbow is an overuse injury to the growing inner part of a young pitcher's elbow, and it shows up as inner-elbow pain that gets worse with throwing. The risk goes up with too much throwing, year-round play, and early breaking balls, and it goes down with sensible workloads, real rest, and patience on the pitches that stress the elbow. But the golden rule overrides everything: elbow pain in a young pitcher means stop throwing and see a doctor. Never trade a healthy arm for one more inning.
Once a doctor has cleared any pain, one thing worth checking is whether his delivery is adding avoidable stress to the arm, because an all-arm motion that doesn't use the legs and body works the elbow harder than it needs to. Film one pitch from the side and upload it, and we'll break down his mechanics frame by frame and show you whether his body is sharing the load. This is a mechanics read, not medical advice, so a doctor always comes first for any pain.

What is Little League elbow?
It's a common name for an overuse injury to the growth plate on the inner side of a young thrower's elbow, caused by the repeated stress of throwing before that area is done growing. It typically affects pitchers roughly ages 8 to 15 and shows up as inner-elbow pain that worsens with throwing. It's a real medical condition that only a doctor can diagnose, so any elbow pain in a young pitcher should be evaluated by a physician.
What are the symptoms of Little League elbow?
The most common sign is pain on the inside of the elbow that gets worse with throwing and doesn't fully go away with rest. There can also be swelling, a loss of full range of motion, trouble fully straightening the arm, or a change in how the child throws to avoid the pain. Any of these means he should stop throwing and see a doctor. General, fading soreness is different from persistent inner-elbow pain.
How is Little League elbow treated?
Treatment is directed by a doctor, but for an overuse condition like this it usually centers on rest from throwing, sometimes for several weeks, followed by a gradual, guided return to throwing under medical and coaching supervision. The most important step is stopping throwing and getting it evaluated rather than pitching through the pain. Never try to manage a young pitcher's elbow pain by continuing to play.
How can you reduce the risk of Little League elbow?
Since it's an overuse injury, the biggest levers are workload and recovery: follow age-appropriate pitch counts and rest days, don't pitch a tired arm, take months off from throwing each year rather than playing year-round, and wait on breaking balls until the mid-teens. These steps reduce risk but can't guarantee a healthy arm. Listening to pain and resting early is part of it too.
Is Little League elbow the same as a Tommy John injury?
No. Little League elbow involves the growth plate on the inner elbow in a still-growing young thrower, while a Tommy John injury refers to damage to the ulnar collateral ligament (UCL) and the surgery that repairs it, more often discussed in older, skeletally mature pitchers. They affect the same general area of the elbow and share overuse as a risk factor, but they're different problems. Only a doctor can tell you which, if either, is involved, so elbow pain always warrants a medical evaluation.
