Well friends you see, my rheumatoid arthritis symptoms stopped as I left Panama City, Panama, Central America . . . Even on the self-controlled HUMIDITY FREE airplane environment, this just with the cabin shut, still on land. I COULD FEEL MY FINGERS AGAIN . . . for the nerves where blocked due to wrist inflammation. Now back at Home in Nicaragua, have been tapering down all medication may I stop Methotrexate COLD TURKEY?
