Localized Pain: A dull, aching pain occurs directly over the affected tendon, which typically becomes much sharper and more severe when the joint is moved or placed under physical stress 2.
Swelling and Tenderness: The tissue immediately surrounding the irritated tendon frequently develops visible fluid swelling, may feel warm to the touch, and is highly sensitive to even light pressure 2.
Joint Stiffness: The affected joint often experiences a significant loss of physical flexibility and a restricted range of motion, which is typically most severe upon waking up in the morning or after long periods of rest 7.
Grating Sensation: A crackling, popping, or grating feeling may be physically felt or heard within the joint during movement, which happens because the swollen tendon can no longer glide smoothly past its surrounding tissues 1.
Muscle Weakness: The muscle attached to the inflamed tendon may feel noticeably weak, making it difficult to perform everyday tasks like gripping objects, lifting items, or climbing stairs 2.
