it is sicca syndrome. i think once you have suffered a urinary tract infection or an STD it is the side effect of this.

Thanks for the reply. What is this syndrome and how can it be cured?

Hi, I am suffering the same, but with a couple of other symptoms thrown in. I have a painful right side of the tongue which comes and goes, neck pain, earache apparently blocked eustachian tube and a couple of other niggly things. The maxilliofacial dr said dry mouth can be anxiety...enlarged lymph nodes even in the groin can also be due to stress I think. Dry mouth can also be sjorgens syndrome from what i've researched. Is your groin lump large/painful to touch and completely fixed in position like mine? It almost feels like a smooth rounded nodule of bone. I am worried about it and will see a Dr this week if it doesn't go down. Let me know how you get on.

Hi
Welcome to Healthcare Magic Forum
Your symptoms suggest that this may be Sjogren's Syndrom. Which is an autoimmune illnes, with no cure, treatment available give relief in symptoms only. You need to see a physician and do some specific tests like ANA, RA factor etc to confirm the diagnosis.
For dry eye you can use eye drops which provide lubrication, also use glares whenever you are outside. Avoid rubbing the eyes, and spending too much time in A/c.
For dry mouth, well plenty of water and fluids is best solution.
Lump in groin has to examined by a physician.
Takecare

As i said earlier, Sjogren's Syndrome has no permanent treatment as such.
You can try homoeopathy for the same, it works well in autoimmune diseases.
But before all of this, you need to confirm the diagnosis by examination and tests.
