I am a 25y old female with dry eyes, mouth. Have had painful, diffuse swollen parotid, treated for parotitis. Consequent swollen eye.;possible sjogrens?

Could be. The symptoms you describe can very well be related to sjogrens. This disease can be diagnosed with certain laboratory data but often requires a biopsy of the salivary glands located in the lip area (minor salivary glands). This can be done easily under local anesthetic in the office by ENT md's.
Yes. Yes. Sjogren's syndrome is a definite possibility. You need a thorough evaluation with a rheumatologist as soon as possible.
Yes. These are classic signs of sjogren syndrome? Further testing would need to be done to verify this.
