Understanding this injury
Post-Concussion Syndrome is what happens when concussion symptoms — headaches, dizziness, brain fog, fatigue, nausea, light and sound sensitivity, neck pain, mood changes — stick around longer than the expected 7-14 days. For many people, symptoms can drag on for weeks, months, or even years if not treated properly.
The old advice was 'rest in a dark room until you feel better.' Modern research has flipped that completely. We now know that prolonged rest after the first 48 hours actually slows recovery, and that targeted, sub-symptom-threshold rehabilitation — addressing the vestibular system, the neck (which is almost always involved), exertion tolerance, vision, and the autonomic nervous system — is the fastest path back to feeling like yourself.
Common symptoms
- Prolonged headaches
- Dizziness and balance problems
- Difficulty concentrating or remembering
- Sensitivity to light and noise
What causes it
- A direct or whiplash-type concussion (sports, fall, MVA, assault)
- Multiple concussions (cumulative effect)
- Cervical spine dysfunction from the same impact (often missed)
- Vestibular system disruption
- Autonomic nervous system dysregulation after head injury
Who's most at risk
- Athletes in contact and collision sports
- Adolescents and young adults (slower recovery than older adults, ironically)
- Women (typically longer recovery than men)
- Anyone with prior concussions or history of migraine
- People with anxiety, depression, or sleep issues
How we treat it
Your PT will perform a comprehensive concussion evaluation looking at vestibular function, oculomotor (eye movement) function, cervical spine, balance, exertion tolerance (with a Buffalo Treadmill or comparable test), and autonomic regulation. We figure out which of those systems is driving your symptoms — usually it's more than one — and build a targeted plan for each.
Treatment may include vestibular and gaze-stabilization exercises, manual therapy and exercise for the neck (often the hidden driver of post-concussion headaches), graded sub-symptom-threshold aerobic exercise (a game-changer in the research), vision therapy referrals when needed, sleep and nutrition coaching, and a step-by-step return-to-school, return-to-work, and return-to-sport progression. We coordinate with your physician and any neurologist or neuropsychologist on your team. Most patients see real progress within weeks, even after months of stuck symptoms.
If your symptoms aren't improving in 2-3 weeks, are getting worse, or starting to limit daily activities, call us or schedule an appointment online today — early intervention almost always means a faster, fuller recovery.
Recovery timeline
Acute cases (caught in the first month) often resolve in 4-6 weeks. Persistent symptoms (3+ months) typically take 6-12 weeks of targeted care to substantially improve. Even very long-standing post-concussion symptoms often respond once treatment finally targets the right systems.
What you can do at home today
- Get on a regular sleep schedule — sleep is when the brain repairs
- Try gentle aerobic exercise daily (below the level that flares symptoms)
- Limit alcohol completely during recovery
- Don't 'cocoon' in a dark room past day 2 — gradual exposure is healing
- Hydrate well and limit caffeine to morning only
These tips support recovery but don't replace a professional evaluation. If you're unsure or symptoms worsen, please reach out.
When to call us right away
Go to the ER for sudden worsening headache, repeated vomiting, seizures, slurred speech, weakness or numbness, unequal pupil size, loss of consciousness, or any change suggesting a second-impact or bleed.
