Hi, no fears about life expectancy or radioactive substance in saaz. Rhumatoid arthritis has specific treatment protocols depending on severity of disease and response to available drugs. These drugs range from non steroidal anti inflammatory drugs, corticosteroids, gold salts to immuno suppressive drugs. Adherence to physician s treatment plan permits evaluation of drug response and suitability. Generally, with a good response to a given drug or drugs, the dose is usually reduced to very minimal doses in the long run and with marked improvement in quality of life and less complications. I suggest you meet your internist/rhumatologist for a proper evaluation and appropriate treatment plan. Thanks and hope this helps, Luchuo, MD.
