Triceps tendinitis is the inflammation or irritation of the tendon that connects the triceps muscle to the elbow.
The discomfort is localized to the posterior (back) side of the elbow, directly above the bony tip.
Point Tenderness: Pain when pressing directly on the tendon just above the elbow point.
Ache with Extension: Sharp pain when fully straightening the arm or pushing against resistance (e.g., push-ups, bench press, or dipping).
Stiffness: A feeling of tightness in the back of the arm, especially after periods of inactivity or first thing in the morning.
Swelling: Occasionally, visible swelling or a small knot may appear on the tendon.
Physical Exam: The doctor will have you perform a resisted elbow extension. If pushing your arm straight against their hand triggers pain at the elbow tip, it’s a strong indicator.
X-rays: Used to rule out a bone spur on the olecranon, which can often rub against and irritate the triceps tendon.
MRI or Ultrasound: These imaging tools can show the thickness of the tendon and identify if there is any "mucoid degeneration" (wear and tear) or small partial tears within the fibers.
Activity Modification: Temporarily stopping exercises like tricep extensions, dips, and heavy pressing. Switching to "neutral grip" movements can sometimes help.
