Sounds like more of an inconvienance than a serious health issue.The yogurt is a mucous forming food,I would stop if it was me to see what would happen.Then reintroduce latter while watching for signs of mucous issues.I have a greenstar2000,and have no pulp issues unless I use the fruit sreen.Which I only use on lemons,and use a strainer before consuming.In the instructions I think they recomend straining all your juice if you desire pulpless juice.I dont mind a little pulp myself the extra fiber is a good thing.I believe Jay Kordich said juicing radishes helped dry up and open up sinuses.You might want to give it a try!Be Wise Be GREEN Be Healthy!!
