Why Are My Concussion Symptoms Getting Worse? Causes & Solutions

Feb 27

Recovering from a concussion can be frustrating, especially if your symptoms seem to be getting worse instead of better. For many people, post-concussion symptoms fluctuate over time, making it difficult to predict recovery. If you’re wondering, "Why are my concussion symptoms not improving?" or "Why do I feel worse now than I did right after my injury?"—you’re not alone.

Understanding what causes post-concussion symptoms to worsen and learning how to address these issues can help you take control of your recovery.

Can Concussion Symptoms Get Worse Over Time?

Yes, post-concussion symptoms can get worse before they get better. While some people experience a steady improvement, others may notice that certain symptoms—such as headaches, dizziness, brain fog, or fatigue—fluctuate or even intensify weeks or months after the initial injury. Here’s why this can happen:

Delayed concussion symptom onset – Some symptoms don’t appear immediately after the injury but emerge days or even weeks later.
Post-concussion fatigue worsening over time – Mental and physical exertion can build up, leading to increasing fatigue.
Exercise-induced concussion symptoms – If your nervous system isn’t functioning properly, exertion can trigger dizziness, headaches, or brain fog.
Autonomic dysfunction – Dysregulation of the autonomic nervous system can lead to issues like POTS (Postural Orthostatic Tachycardia Syndrome), causing worsened symptoms when standing or exercising.
Unresolved musculoskeletal injuries – Neck injuries, whiplash, or poor posture can contribute to persistent headaches and dizziness.

If your symptoms are worsening, it’s important to identify the underlying cause and adjust your recovery approach accordingly.

Common Reasons Why Post-Concussion Symptoms Worsen

1. Overexertion and Pushing Too Hard

Many people assume that once a few weeks have passed, they can return to normal activities. However, jumping back into intense exercise, screen time, or mentally demanding tasks too soon can overload your brain and nervous system.

Signs of overexertion:

Headaches after physical or mental activity
Increased dizziness or nausea after working on screens
Feeling exhausted after minor exertion

What to do: Gradually reintroduce activity using interval-based strategies to rebuild tolerance without overwhelming your system.

The Concussion Solution offers guided recovery techniques to help you regain function at the right pace.

2. Delayed Concussion Symptom Onset

Some post-concussion symptoms don’t show up right away. Inflammation, nervous system dysregulation, and cumulative stress can lead to new or worsening symptoms weeks or months later.

Symptoms that may appear later:

Brain fog and difficulty concentrating
Mood changes or anxiety
Sensitivity to light and sound

What to do: Listen to your body and seek structured rehabilitation strategies to address persistent issues.

3. Autonomic Dysfunction and Blood Flow Issues

If standing up quickly makes you dizzy or lightheaded, or if exercise makes you feel worse instead of better, autonomic dysfunction might be at play. Blood pressure regulation can be impaired after a concussion, leading to conditions like POTS.

How to improve autonomic function:

Gradual, structured physical activity to retrain blood flow regulation
Breathwork and vagus nerve stimulation to support nervous system balance
Specialized therapy, such as LiveO2 oxygen therapy, to optimize brain function

The Concussion Solution provides step-by-step guidance on how to address autonomic dysfunction and safely rebuild your tolerance to exercise.

4. Neck and Spine Dysfunction

Headaches and dizziness are often caused by underlying neck issues after a concussion. Even if imaging doesn’t show a serious injury, muscle tension and joint dysfunction can create persistent symptoms.

Signs of cervicogenic headaches:

Pain starting at the base of the skull and radiating forward
Increased headache intensity after sitting or working on a computer
Stiffness or discomfort in the neck and shoulders

What to do: A skilled physical therapist can help resolve these issues with manual therapy, postural retraining, and targeted exercises.

How to Stop Post-Concussion Symptoms from Getting Worse

If your symptoms are worsening, don’t panic—there are proven strategies to help your brain and body recover. Here’s what you can do:

Pace yourself – Avoid pushing too hard, too soon. Use structured intervals to gradually build your activity tolerance.
Support your nervous system – Techniques like breathwork, hydration, and autonomic retraining can help regulate blood flow and energy levels.
Address musculoskeletal issues – Physical therapy for neck and spine dysfunction can relieve headaches and dizziness.
Follow a guided recovery program – The Concussion Solution provides evidence-based strategies to help you navigate post-concussion recovery effectively.
