My nine-year-old son was diagnosed with dientamoeba fragilis in November. For the past two-plus months he has experienced symptoms of frontal headache and bilateral shoulder/upper arm pain. These have been fairly low-level, but constant. No fever. He also has been fatigued. He was on Flagyl for seven days but stopped due to severe G-I symptoms.
He's been seen by his pediatrician, two neurologists, an infectious disease doctor and an orthopedist. We can't get any concensus about whether the headache and shoulder pain are caused by the parasite, or if there's something else going on. His eosinophils are slightly elevated. His white blood count is marginally low. Everything else is normal. He's been tested for mono, strep, and lyme disease, all negative. Had a head CT scan and shoulder x-rays. Fine. Thyroid function is normal. Complete metabolic panel all fine. Sed rate has been either zero or one.
Does anybody know if it's conceivable the parasite is producing the headache and shoulder pain?
