Overview
What is concussion / post-concussion syndrome?
A concussion is a mild traumatic brain injury caused by a blow to the head or body, common in contact sports and falls — most resolve in weeks, some develop persistent post-concussion symptoms. Symptoms can develop gradually or after a specific injury, so early evaluation matters when function starts to decline.
Most patients with concussion / post-concussion syndrome improve with conservative care — targeted physical therapy, image-guided injections, bracing or supportive footwear when relevant, and activity modification. When conservative care isn't enough or imaging shows structural injury that won't heal on its own, our specialists offer the next-step procedures discussed below.
Below, we walk through the anatomy involved, the symptoms and causes we most often see, how we diagnose concussion / post-concussion syndrome, and the full range of treatment options — from the simplest to the most involved.
Patient education
Watch: Concussion
This is a serious brain injury. It happens when your brain bumps back and forth violently inside your skull. A concussion can affect the way your brain functions. It can cause permanent problems.

Sports injuries can affect any joint — cartilage, ligaments, tendons, and bone.
Anatomy
Inside the sports injury.
Sports injuries can affect any joint, but they share a common pattern: a sudden overload or repetitive stress that exceeds what the tissue can absorb. The damaged tissue might be cartilage, a ligament, a tendon, a meniscus, or bone. Our sports medicine team treats the injury — and just as importantly, finds the mechanics or training load that caused it so it doesn't come back.

Diagnostics
How we diagnose concussion / post-concussion syndrome
You want answers, fast — and we're built to give them. Most patients leave their first LAOSS visit with a clear diagnosis and a written plan, not another referral chain.
Here's what your initial visit for concussion / post-concussion syndrome typically looks like:
- Detailed history — when it started, what makes it better or worse, what you've already tried
- Focused exam of the sports injury — range of motion, stability, strength, specific provocation tests
- On-site imaging at most offices: X-ray for bone, ultrasound or MRI when soft-tissue detail is needed
- A written plan with options ranging from conservative care to surgical procedures, in plain English

FAQ
Common concussion / post-concussion syndrome questions
- We start with a focused orthopedic exam and detailed history. X-rays are usually done in-office; MRI or ultrasound is ordered when soft-tissue detail is needed. Most patients leave the first visit with a clear diagnosis and a written plan.
- Most concussion / post-concussion syndrome patients improve with conservative care — therapy, bracing, medication, and image-guided injections when appropriate. Surgery is reserved for cases where structural injury or persistent symptoms warrant it, and we explain every option before any decision.
- If sports injury pain lasts more than a few days, limits movement, or interferes with daily activities, it's time to see a doctor. Sudden injuries, swelling, or weakness should be evaluated right away.
- If you have a PPO plan, no referral is needed — book directly with any of our specialists. HMO plans require a referral from your PCP. If you are unsure, call us at (323) 264-7600 and our team will walk you through it.
