Armpit Trigger Points

Armpit trigger points refer to specific, irritable nodules or hyperirritable areas within the fascia of the shoulder muscles, often resulting in referred pain in the arm and shoulder region. These points can be very tender, causing a dull ache or burning sensation, and are usually associated with muscle spasm and restricted movement in the shoulder.

Why Do Armpit Trigger Points Happen?

Armpit trigger points can form due to a variety of factors, including:

Poor posture: Slouching or slumping forward, especially when seated with the arm supported only by the wrist, can put pressure on the shoulder muscles and trigger trigger points.
肩袖撕裂: Armpit trigger points can develop after a tear in the rotator cuff muscle, which can lead to increased tension and pain in the armpit region.
Repetitive motions: Holding objects in the hand, such as a telephone, and repetitive lifting or movements of the arm can cause micro-trauma to the shoulder muscles, leading to trigger points.
Whiplash: Accidental impacts to the shoulder during a vehicle crash can cause stretch and strain to the shoulder muscles, potentially triggering trigger points.
Muscle tightness: Tightness in the upper shoulder muscles, such as the subclavian muscles, can reduce movement and increase the risk of trigger point formation.

How to Identify Armpit Trigger Points

Armpit trigger points can be identified by:

Palpation: A tender nodules or area of increased tension that cause pain when compressed.
Localized pain: A sharp, shooting pain that is often referred to the ipsilateral (same side) shoulder or upper arm.
Referral patterns: The pain often radiates or spreads to the shoulder region from the site of the trigger point.
Muscle spasm: A tightness or contraction in the shoulder muscles, often accompanied by aching or cramping.
Changes in movement: Limited mobility or restriction in movements that were previously normal.

Treatment for Armpit Trigger Points

Treatment for armpit trigger points typically involves a combination of:

Manual therapy: Such as triggers point release or stretching techniques to alleviate tension and spasm in the shoulder muscles.
Massage: A gentle massage can help to release muscle tension and improve circulation in the affected area.
Ice and heat: Applying cold or warm packs can help to reduce inflammation and muscle spasm, respectively.
Pharmacology: Over-the-counter pain relievers or prescription medication may be necessary to manage pain and inflammation.
Heat therapy: Applications of heat, such as using a heating pad or infrared lamps, can help relax muscles and improve circulation.
Physical therapy: Techniques that promote movement and improve muscle flexibility can be beneficial.
Posture correction: Learning and practicing good posture habits can help to reduce the risk of developing trigger points.
