When inflammation and swelling affect your joints, besides pain, it is called rheumatoid arthritis. In addition, a blood test may reveal "rheumatoid factor" to be present. In this case, the common tiny round worms have invaded your joints. These are Ascaris, Ancylostomas, Strongyloides, and Trichinella. Their eggs are everywhere around us, in dust and dirt and the filth under fingernails and our own bowel movements.
Superior sanitation is your first defense. Rinse fingernails in alcohol after cleaning up bowel movements or changing diapers. Never, never, tolerate long fingernails in any family member. If this discipline can't be enforced, do not allow food preparation by "long nails" unless gloves are worn. He or she may not be getting ill (yet) from the family parasites, but you are. Of course, you can kill them with a NEOClark (internally, not the ones under the nails) but that is after you have been infected. They are easily picked up again. It would be wise to zap for roundworms every week, just in case.
Make sure your pet is treated with parasite herbs or by zap-per as well. A pet that goes outdoors will quickly (the very next day) bring these roundworms into the house again. Give away your pets if possible.
Check for dental problems. Do the Dental Clean-Up. Then do a Kidney Cleanse and Liver Cleanse.
You may relieve your pain and begin to heal immediately after zapping but it is wise to do all the health programs, anyway. Change your diet. Reduce phosphate, start using sterilized milk for calcium. Switch to fish from meats. Drink much more water. Use only harmless beverages (see Recipes) and foods. Switch to toxin-free body products. Live in a non-toxic house. Stay on a maintenance parasite program of herbs, and zap regularly. Stay on the kidney cleanse for three to six weeks and repeat a one-week session every few months to keep removing deposits which may also choose these sick joints to settle in. Knees are a favorite location for rheumatoid arthritis. Knees are very dependent on kidneys.
To summarize, do everything as for osteoarthritis, emphasizing the roundworm parasites for elimination.
