Pain Under Right Collarbone in Females: Causes and When Massage Helps

Pain under the right collarbone in females is most often caused by tightness or strain in the chest-wall muscles — specifically the pectoralis minor, subclavius, or scalenes. For confirmed musculoskeletal causes, RMT massage addresses these muscles directly, and most clients see meaningful improvement within 2-4 sessions.

If that sounds like your situation — gradual onset, worse with specific movements or prolonged posture — read on. The most important thing to do first is rule out anything requiring immediate care.

When to call 911 first

Before exploring musculoskeletal causes, rule out anything more serious. Call 911 if your collarbone or upper-chest pain comes with any of the following:

• Crushing, squeezing, or heavy pressure in the chest
• Pain radiating into the jaw, neck, left arm, or upper back
• Shortness of breath
• Cold sweat, nausea, or sudden lightheadedness

A note for women specifically: Heart attack symptoms in women more often present as upper-chest, neck, jaw, or shoulder pain — not the classic crushing chest sensation most people picture. Cardiac causes of collarbone-area pain are far more common on the left side than the right, but right-sided chest pain that comes on suddenly or feels like pressure rather than soreness still warrants a check.

Dull, ache-like pain that’s tied to specific movements and has built up gradually? Most likely musculoskeletal. Read on.

Which muscles are actually behind most right collarbone pain

The clavicle is a bone, not a muscle — but several muscles attach to it or run directly underneath it. When these muscles get tight, strained, or develop trigger points, pain refers to the collarbone area:

Subclavius sits directly under the clavicle and is the most overlooked source. Trigger points here send aching pain along the clavicle and sometimes down into the arm. It tightens from forward head posture, carrying bags on one shoulder, and repetitive overhead movements.

Pectoralis minor connects the ribs to the coracoid process of the scapula, running under the clavicle on its way. When it shortens from desk work or chest-dominant training, it pulls the shoulder forward and compresses everything passing beneath the clavicle. Tight pec minor is one of the most common findings in anterior shoulder and collarbone pain for people who sit a lot.

Anterior scalenes run along the side of the neck and attach to the upper two ribs. Tightness or trigger points here can compress the brachial plexus and subclavian artery as they pass under the clavicle — this is thoracic outlet syndrome, which produces collarbone pain alongside arm heaviness and sometimes tingling in the fingers.

Upper trapezius and levator scapulae don’t directly cause collarbone pain but often need treatment because they’re reinforcing the posture — elevated, rounded shoulders — that drives the problem upstream.

An RMT assessment will identify which of these is the primary driver. It’s usually not just one.

What to try at home first

If the pain has been building gradually and isn’t severe, these are worth doing consistently for 2-3 weeks:

Doorway pec stretch: Stand in a doorframe, arms at 90 degrees, lean gently forward until you feel a stretch across the front of the chest. Hold 30-45 seconds, 3-4 times a day. This is the single most effective self-care move for tight pec minor.

Scalene stretch: Tilt your head away from the painful side, then rotate slightly upward. Hold 20-30 seconds. Keep the shoulder on the stretched side down. Targets the anterior scalenes specifically.

Posture resets at the desk: Every 30-45 minutes, roll your shoulders back and down and gently draw the shoulder blades together. This doesn’t fix the underlying tightness, but it interrupts the postural load on the chest-wall muscles.

Moist heat: 15-20 minutes on the chest-wall and upper shoulder before stretching helps relax the muscles. Use ice in the first 48 hours of a new acute injury; heat for chronic, stiff presentations.

If symptoms aren’t improving within 2-3 weeks, or if they’re affecting sleep or limiting arm movement, book an RMT assessment.

When to see an RMT

An RMT can do things self-care can’t reach — work directly on the subclavius (inaccessible to self-massage), release the pec minor with specific cross-fiber techniques, and identify what’s maintaining the problem rather than just where it hurts.

Book a session if:

• Pain has persisted more than 3-4 weeks despite consistent stretching
• You notice numbness, tingling, or heaviness in your arm alongside the collarbone pain — possible thoracic outlet involvement, worth getting assessed
• The pain wakes you at night or limits overhead movement
• You’re back in the gym and the collarbone keeps flaring under load

Sarah’s recovery from collarbone pain

Sarah, an active runner and swimmer from Edmonton, started experiencing pain under her right collarbone after a particularly intense workout session. She ignored it at first, but it soon became difficult to lift her arm without pain. After consulting a massage therapist at Athlete’s Choice Massage, Sarah followed a treatment plan that included targeted massage, heat therapy, and gentle stretches. Within a few weeks, her pain had significantly reduced, and she was back to training without restriction.

Treatment at Athlete’s Choice Massage

At Athlete’s Choice Massage, our RMTs approach collarbone pain systematically — not just treating where it hurts. A typical first session includes:

• Direct subclavius and pec minor release
• Anterior scalene and upper trap work
• Assessment of shoulder blade mechanics contributing to the pattern
• Specific home-care guidance for your posture and activities

Therapeutic massage is the starting point for most collarbone and upper chest presentations. For cases with significant postural imbalance or deeper muscle involvement, deep tissue massage addresses layers that lighter pressure doesn’t reach.

Book in Edmonton or Sherwood Park

Athlete’s Choice Massage operates four locations across the Edmonton area:

• West Edmonton — near West Edmonton Mall and Stony Plain Road
• Old Strathcona — near Whyte Ave and the U of A
• Downtown Edmonton — central business district
• Sherwood Park — Strathcona County

Frequently asked questions

What causes pain under the right collarbone in females?

Most commonly tightness or strain in the pectoralis minor, subclavius, or scalene muscles. Poor posture — rounded shoulders and forward head — is a frequent driver because it shortens the chest-wall muscles and compresses the structures under the clavicle. Nerve irritation, thoracic outlet syndrome, and less commonly costochondritis can also present as right collarbone pain. Sudden severe pain warrants immediate medical assessment to rule out cardiac causes, though these are far more common on the left side.

When should I see a doctor for right collarbone pain?

Go to emergency immediately if the pain is sudden and severe, or comes with chest pressure, shortness of breath, jaw or arm pain, cold sweats, or lightheadedness. For gradual, movement-related pain that worsens with specific postures or activities, a doctor or RMT assessment is appropriate. Most right collarbone pain without associated cardiac or respiratory symptoms is musculoskeletal.

Can massage therapy help with right collarbone pain?

Yes, for confirmed musculoskeletal causes. An RMT can release the pec minor and subclavius — the two muscles most commonly responsible for right collarbone pain — along with the anterior scalenes and upper trap. Most clients at Athlete’s Choice Massage see meaningful improvement within 2-4 sessions. Four Edmonton-area locations, direct billing to most Alberta health benefit plans.

How long does pain under the right collarbone take to heal?

Acute strain usually resolves in 2-6 weeks with rest and treatment. Chronic postural causes take longer — 6-12 weeks — and improvement depends on addressing what’s maintaining the problem (desk posture, carrying habits, shoulder position during training) alongside the massage work itself.

Is RMT massage covered by Alberta health benefits?

Most extended health benefit plans in Alberta cover Registered Massage Therapy. Coverage amounts and referral requirements vary by plan. Athlete’s Choice direct bills to most major Alberta insurers and Alberta Blue Cross — see our direct billing page for current providers.
