Antibiotics can certainly provide symptom relieve for symptoms caused by biological problems. Sjogren's is an auto-immune disease and symptoms will most likely NOT be decreased by using antibiotics. Since you seem to have relief via the use of antibiotics, it's most likely you don't have Sjogren's.
If you are concerned about
Sjogren's, best to see a rheumatologist (the masters of the auto-immune world; Sjogren's is an auto-immune disease) for a full workup.
