I have sicca symptoms so have to chew gum from morning till night. this is causing me a lot of gas & pain and worsening my prolapse. is there any medicine that relieve gas thats safe to take daily? doesnt matter what i do or dont eat i am constipa?

It's so hard, the symptoms of dryness are very intrusive on life. Talk to your rheumatology consultant (who may think you are fine!) and mention your discomfort. Constipation as you know is part of the dryness; increasing water intake will help some. Things for your comfort are not necessarily medication. Best wishes

Try simethicone (Gas-x). Try to adjust diet, exercise, and try psyllium for constipation
