Chronic pain & fatigue in children · Functional medicine

When a child is too tired or in too much pain to live normally, keep looking.

Chronic pain and fatigue in children can involve sleep, inflammation, gut health, infections, Lyme, mold, nutrient status, nervous-system sensitization, and post-viral changes. We help families build a careful map.

What parents are facing

Chronic pain & fatigue is rarely just one symptom.

Families usually arrive here after months or years of treating isolated symptoms while the bigger pattern keeps showing up at home. We look at the timeline, the body systems involved, the testing already done, and the clues that may have been missed.

  • Your child has symptoms that keep returning, shifting, or affecting daily life.
  • Standard testing may have ruled out urgent problems without explaining why this is still happening.
  • You need a clinician who can connect gut, immune, food, infection, sleep, nutrient, and environmental clues.
Root-cause map

What we investigate before recommending a plan.

Timeline

When symptoms started, what changed before the first flare, what makes symptoms better or worse, and what has already been tried.

Gut and food patterns

Constipation, reflux, picky eating, bloating, food reactions, microbiome balance, and gut barrier clues.

Immune load

Recurrent infections, allergies, autoimmune history, inflammation, PANS/PANDAS clues, and post-viral or tick-borne patterns.

Environment

Mold, water damage, seasonal triggers, chemical exposures, sleep space, school exposures, and other hidden stressors.

Nutrient status

Iron, vitamin D, magnesium, zinc, omega-3s, methylation needs, and other deficiencies that can affect resilience.

Real-life fit

What your child will tolerate and what your family can realistically sustain without burning out.

Simple plan

Start with the next right clinical step.

The free consult helps determine whether your child is a fit for a full intake, focused gut testing, 4-month concierge care, or a different referral first.

  1. 01

    Start with fit.

    Tell us what your child is dealing with and what care you have already tried.

  2. 02

    Map the drivers.

    If we work together, we review the timeline, symptoms, labs, medications, diet, sleep, and environment.

  3. 03

    Follow a written plan.

    You leave with prioritized next steps for testing, food, supplements when appropriate, routines, and follow-up.

Clinical deep dive

What parents need to know about chronic pain & fatigue.

Children should not be written off as lazy, dramatic, or anxious.

Chronic pain and fatigue can quietly shrink a child’s world. School attendance drops. Sports disappear. Screens become the only manageable activity. Parents hear that labs are normal, anxiety is probably involved, or they should wait it out.

Sometimes anxiety is part of the picture. That does not mean the body is fine.

What we look for.

We review onset, infections, EBV (Epstein-Barr virus) or COVID history, other viral exposures, tick exposure, mold exposure, sleep quality, pain location, headaches, dizziness, GI symptoms, food reactions, menstrual patterns, medications, school stress, activity tolerance, flares after exertion, prior labs, and specialist workups.

We also look for red flags that need conventional evaluation: weight loss, fever, neurological changes, inflammatory joint swelling, blood in stool, severe weakness, fainting, chest pain, or rapid worsening.

Functional medicine map.

Potential contributors include post-viral inflammation (EBV reactivation is one of the most common patterns we see, along with post-COVID and other viral triggers), Lyme or tick-borne illness, mold or biotoxin exposure, nutrient deficiencies, iron/ferritin issues, mitochondrial stress, gut inflammation, food triggers, sleep disruption, autonomic nervous-system strain, and autoimmune patterns.

Testing depends on the case. It may include basic labs, inflammatory markers, nutrient status, stool testing, tick-borne evaluation, mold testing, thyroid markers, or referral to specialists.

How Calm Wellness helps.

These cases are usually not quick. They often fit the 4-Month Concierge Package because the plan needs phases: stabilize, test carefully, support sleep and nutrition, address gut and inflammation, pace activity, and coordinate with other clinicians.

The goal is a child who can participate in life again, with parents who understand what to watch and what to do next.

Common questions

Things parents ask us about this.

What if my child's labs are normal but they still feel terrible?

Normal basic labs can be reassuring, but they do not always explain chronic fatigue, pain, post-viral symptoms, gut dysfunction, sleep disruption, mold exposure, Lyme history, nutrient needs, or nervous-system sensitization. We review what has been ruled out and what has not been investigated yet.

How long does chronic pain or fatigue support take?

It depends on the drivers and how long the pattern has been present. Some families notice early wins in sleep, digestion, or energy within weeks. More layered cases involving infection history, mold, autoimmune patterns, or long-term deconditioning usually need a longer phased plan.
