I am a long retired doctor who has had SS for about 30 years and besides the rheumatoid arthritis, dry eyes and mouth, also have a very intermittent (once every 2 to 4 weeks) complete inability to swallow food that does not reach the stomach and has to come back up and lasts some 6 to 12 hours. It is difficult to imagine that any drug would help. I already take methotrexate weekly, prednisolone, hydroxychloraquine, salazopyrin and meloxicam. I also get lip ulceration about once a year that takes months to heal. I would be happy to correspond with any other sufferers.
