Throwing Shoulder Pain: What Active Adults Should Check

Written by Dr. Tim Berreth, DPT

Shoulder pain during throwing usually shows up at a specific point in the motion, most often late cocking, acceleration, or follow-through, and each phase places different demand on the rotator cuff, the labrum, and the muscles that control the shoulder blade. Which phase hurts and what the pain feels like (sharp, deep, catching, or simply fatigued) helps narrow down what is actually happening, rather than treating every case of "shoulder pain when I throw" as the same problem.

COMMON CONTRIBUTORS

  • Rotator cuff overload. The cuff works hardest decelerating the arm after release. Overuse or a strength deficit here is one of the more common findings in throwing shoulder pain.

  • Labral irritation. Repeated stress at the back or front of the labrum during cocking and follow-through can cause deep, sometimes catching pain, particularly with high throwing volume.

  • Scapular control deficits. If the shoulder blade does not position and stabilize well during the throw, the shoulder joint itself absorbs more force than it should.

  • Loss of internal rotation range (GIRD). Throwing shoulders commonly develop a shift in rotational range over time. When that shift becomes excessive, it is associated with a higher rate of shoulder problems.

  • Volume or intensity spikes. A sudden increase in throwing frequency, distance, or velocity without a matching increase in shoulder capacity is one of the more modifiable risk factors.

WHAT YOU CAN SAFELY TRY

  • Note exactly which phase of the throw hurts (cocking, release, or follow-through) and what the pain feels like. This is useful information for an assessment.

  • Reduce throwing volume and intensity temporarily rather than pushing through pain, then rebuild gradually.

  • Add rotator cuff and scapular strengthening work outside of throwing sessions.

  • Warm up the shoulder and thoracic spine before throwing rather than starting cold.

  • Track whether rest days between sessions are actually allowing recovery or whether volume has crept up faster than the shoulder is adapting.

SIGNS THIS SHOULD BE ASSESSED

Get the shoulder assessed if pain occurs on nearly every throw, if velocity or control has noticeably dropped, if there is pain at rest or at night, if the shoulder feels like it catches or shifts during the motion, or if a period of reduced throwing has not led to improvement.

WHEN IMAGING OR REFERRAL MAY BE APPROPRIATE

Imaging or a referral becomes more appropriate when pain and performance loss persist despite a genuine reduction in throwing load and a period of targeted rehab, when there are mechanical symptoms such as catching or a sense of instability, or when a labral tear or significant rotator cuff injury is suspected based on the exam.

FREQUENTLY ASKED QUESTIONS

  • Not necessarily. Rotator cuff overload, labral irritation, and scapular control deficits can all produce similar symptoms. An assessment is what distinguishes between them.

  • Generally not at the same volume. Continuing to throw through pain at full intensity tends to reinforce the same overload pattern. A temporary reduction in volume paired with targeted strengthening is usually more productive than pushing through.

  • GIRD refers to a loss of internal rotation range in the throwing shoulder compared to the non-throwing side. Some shift is normal and expected in throwing athletes. An excessive shift is associated with higher injury rates and is worth addressing as part of a plan.

  • It depends on the underlying contributor and how early it is addressed. Cases caught early, with load management and targeted strengthening, often improve over several weeks. Cases with a suspected structural injury take longer and may need further workup.
