Keep in mind that many patients infected with parasites have no symptoms other than occasional flatulence, nausea or maldigestion. Allergy Inhalant and food allergies can both contribute to chronic myofascial pain. Food allergies are common and potent and should be considered as a possible cause of Myofascial reactions. Travell states that skin tests are unreliable in determining food allergies. We use serum IgE and IgG testing.
Some physicians prefer IgA testing.
It is more expensive and the clinical results following IgG and IgE findings seem to be adequate. Some patients have an idiosyncratic reaction to ingestion of alcohol causing an attack of myofascial pain soon after or the day following the ingestion. Trigger points activated by sleep position can cause impaired sleep. Impaired sleep can help perpetuate trigger points. Radiculopathy can activate trigger points in the area of radicular pain.
