Joint Pain Without Inflammation
Having joint pain in multiple joints without inflammation is calledpolyarthralgia.
This is common in people who get osteoarthritis as they get older.
It happens when inflammation affects joints in the body.
The symptoms can be constant or may flare up when the underlying inflammatory condition flares up.
Autoimmune Disorders
Polyarthritis is most often triggered by autoimmune disorders.
The autoimmune disorders most commonly associated with polyarthritis include:
Polyarthritis may also be seen in the inflammatory disordergout.
Illness
Polyarthritis can also occur as part of an acute illness.
In these cases, the inflammation may move between more than one joint.
Illnesses linked to polyarthritis include:
Diagnosis
Polyarthritis is most commonly related to an underlying disease.
People with RA tend to have symmetric symptoms.
Those with psoriatic arthritis often have asymmetric symptoms.
Blood Tests

Your provider can also test you for viruses if they think your symptoms could be related to an infection.
These are available over-the-counter (OTC) with a prescription.
Your provider might also prescribe a higher dose if you need it.
Prescription
If you need more treatment than OTC medications, your provider might recommend some prescription medications.
These medications help slow the course of autoimmune diseases.
For example, providers may prescribe methotrexate to reduce joint damage because of polyarthritis.
They change the immune system to reduce inflammation.
Corticosteroidscontrol inflammation and can help with pain.
you might take steroids orally or by injection.
However, they should only be used in the short term because they can cause serious side effects.
