Multiple sites of tendon inflammation may be a form
of Enthesitis. Family history is an important part of the evaluation. Do you have any skin related symptoms of
psoriasis involving the scalp or nails.?
Ultrasound of the affected tendons can show sign of
inflammation. I suffered multiple tendinitis sites for
years before being diagnosed with psoriatic arthritis.
Skin signs were subtle and well controlled such that
they were not apparent to my first rheumatologist.
There are no typical lab findings in PsA.
