Hi J.,
What I'm about to tell you is gross and many will dismiss this because it's not something we like to hear. I've recently been reading about human parasites and recall reading that eating bizarre things can sometimes mean a parasitic infection. I realize it sounds crazy but nearly 80-90% of humans have parasites and don't realize it. I can't find the article with that specific symptom listed but these are some of the many symptoms that parasites can cause.
Parasite Signs, Adults, Children
Allergies, Many allergies are caused by worm infections. Tissue becomes inflamed and reactions to foods are the result when eosinophils (white blood cells) are increased due to them. Extreme skin rashes with blisters and food allergies or sensitivities may result.
Anemia, Worms leach nutrients from bodies causing anemia. When they are present in large numbers, they can create enough blood loss to cause anemia or iron deficiency in some people.
Constipation, Some worms can obstruct certain organs like the colon causing constipation, liver and the bile duct.
Diarrhea, Most of the time diarrhea is nature's way of removing toxins.
Fatigue, Symptoms include tiredness, flue-like symptoms, apathy, depression and lack of concentration.
Gas and Stomach Bloating, Some parasites live in the upper intestine, which can cause both gas and stomach bloating.
Immune Dysfunction, Parasites depress the immune system by decreasing immunoglobulin.
Nervousness, The waste products from parasites irritate the nervous system, resulting in anxiety and restlessness.
Other Signs of Parasites in Children
Blisters appear on the inside of the lower lip, wiping of the nose, restlessness and grinding of the teeth at night, dark circles under the eyes, hyperactive, bed wetting, headaches, sensitive to light, twitching eyelid, gum, rectum, or nose bleeding are signs they may have parasites.
You may want to consider trying this product to see if the symptoms subside. http://www.mountainmeadowherbs.com/pararid-p-79.html I have learned that parasite testing is highly inaccurate and many receive negative results when they indeed have parasites.
I am throwing this information out there because I've recently learned that my dd has parasites. She had been plagued by dark circles under her eyes, an itchy nose and adbominal pain(all clear symptoms). We've been dealing with doctors and specialists, blood work, various testing (all with negative results) for the past 7 months...exhausting, time consuming and a waste of money. Not one of them mentioned parasites.
I feel fortunate to have learned about parasites and have started my daughter on a supplement & cleanse. Since starting this, her abdominal pain is gone and the dark circles are diminishing. Since reading more about they symptoms parasites cause I'll do the cleanse for our entire family to see if symptoms we are exhibiting subside before paying a medical professional to give me the run around again.
I hope you find answers for your little man. My 21 month old has a thing for side walk chalk so I know this is frustrating. I'll let you know if that subsides after her cleanse.
Peace,
J.
