A doctor may ask about any symptoms that are being experienced and conduct a physical examination. The doctor may attempt to move the tendon and if the tendon sheath has become inflamed and swollen, a creaky sound could be heard.
If a specific point on the tendon is tender and swollen, this is a high indicator of tendinitis.
if the problem still persists, after attempting rest, applying ice or heat, and over the counter medications, the doctor may recommend additional testing.
A diagnosis can be confirmed by x-ray... if calcium deposits are present around the tendon, this is an indicator of tendinitis.
Other testing methods can be used as well, like an MRI or ultrasound and can confirm any swelling around the tendon sheath.
