Rheumatoid arthritis, known as a progressive, auto immune disorder, is caused due to living amoebic, protozoal and / or other opportunistic pathogens - inside your bloodstream, joints, distorted air element (vata) and resultant toxins (Aam) in the body. These Vata and Toxins accumulate in the soft issues, small and / or large joints and irritate them, thus putting pressure on the nerves and veins in that area. Hence the area becomes red, swollen and stiff and extemely painful. The nerves cannot pass signals smoothly and hence, the condition gets aggravated causing excessive pain and discomfort.
