* Medical history
* Physical examination
* Blood tests

## When Should You Get Checked?
Consider medical evaluation if you have persistent dry eyes or dry mouth together with symptoms such as:
* Joint pain
* Severe fatigue
* Recurrent salivary-gland swelling
* Numbness or tingling
* Frequent dental problems
* Persistent cough
* Unexplained rashes
The more symptoms occur together, the more useful a medical evaluation can be.
