Abstract: A method of treatment of pain from inflammatory diseases such as arthritis is disclosed. The affected areas of the patient are shielded from high frequency electromagnetic radiation while permitting low frequency electromagnetic radiation to reach the affected areas. The method may be accomplished by applying a radiation-shielding textile for an extended period of time, either by fashioning a garment from the textile or using a sheet or cover, or fashioning a wrap. The radiation-shielding textile found to be suitable is a cloth woven of yarn consisting of a textile fibre, such as nylon, and from two to thirty-five percent by weight of electrically conductive filament, preferably stainless steel.
