Pulled Shoulder Muscle

The shoulder is a ball-and-socket joint. The shoulder has several muscles that help it move and allow a wide range of motion. A strain or pulled shoulder muscle can affect the slightest movements, making simple activities difficult and painful. Pulling a muscle in the shoulder can be caused by an injury, overuse, and general wear and tear. Minor shoulder injuries usually heal on their own with rest and self-care. Severe shoulder muscle injuries should be addressed by a medical professional.

Pulled Shoulder Muscle Causes

Pulling a muscle in the shoulder can happen quickly. This could be from falling on the shoulder, an auto accident, or a work accident. It can develop after weeks, months, and years of repetitive motion and overuse. It is common among individuals that play certain sports or jobs that require repetitive activities with the shoulders. They can also happen with no apparent cause. Treatment and recovery depend on the type and severity of the injury.

How to Tell If It’s a Pulled Muscle

It can be hard to tell the cause unless the individual has experienced the specific type of pain before. Otherwise, it is recommended to consult a medical professional like a physical therapist or chiropractor. This is because shoulder pain can be caused by inflammation of the tendons and joints and/or the joint itself.

Pulled Muscle Shoulder Symptoms

Pain due to a pulled muscle is characterized by:

• Tenderness
• Dull, sore, or aching pain.
• Sometimes it can cause shooting pain between the shoulder blades in the front or back.
• Pain when the shoulder is at rest.
• Pain when the specific muscle is used.
• Swelling of the area.
• Shoulder instability.
• The shoulder feels fragile.
• Movement causes pain.
• A bump may develop at the top of the shoulder near the end of the collarbone.
• Inability to use the muscle at all.
• If the pain is persistent, it could signify that there is something other than a pulled muscle like a pinched nerve or a joint issue.

Treatment and Recovery Options

Treatment and recovery vary and depend on the severity of the pull and the individual’s overall health. Many find that their pain is reduced with self-care in 2 or 3 weeks. Chiropractic treatment for a pulled shoulder muscle can provide relief within 1 or 2 weeks.

Self Care

Depending on the severity of the pull and how much pain is being experienced, individuals could be recommended to take an NSAID like Ibuprofen to reduce pain and swelling. Self-care can include:

Ice To Reduce Swelling

• Applying ice or a cold pack to the area can help reduce swelling.
• Place a cloth or towel between the skin and the cold pack.
• Apply it for 20 minutes an hour.
• The swelling should reduce in a day or two.

Rest

• It is recommended to rest the shoulder for no more than 2 or 3 days.
• This begins the healing process and prevents worsening the injury.

Wrap or Sling

• During rest days, it can be hard to keep the shoulder from moving.
• To avoid this, use a shoulder wrap or a sling to support the arm.
• However, they should not be used for more than 2 or 3 days.

Gentle Stretching

• It is essential to get the muscle working again after 2 or 3 days of rest.
• Stretches will help the muscle group heal and gain strength.
• Not stretching the muscle could prolong recovery and worsen the injury, and possibly cause new injuries.

Stretches For a Pulled Shoulder

Stretching a pulled shoulder muscle after a few days of rest is recommended because not working out the injured muscle can cause more problems. Not using the muscle can cause it to atrophy, which will take longer to heal, and the surrounding muscles become weak.

Pendulum Stretch

• Slightly bent support the body by placing the unaffected arm on a table or chair.
• Let the injured arm hang straight down.
• Swing the arm in small circles clockwise as far as the pain or discomfort allows.
• Perform for 1 minute.
• Go counterclockwise for one minute.
• Repeat 4 to 8 times throughout the day.

Chiropractic

If self-care is not providing sufficient relief, then chiropractic treatment is recommended. A doctor of chiropractic can advise on the best treatment options and get to the root of the issue. Chiropractors have a treatment arsenal of modalities and approaches to help treat pulled muscles. These include:

• Chiropractic adjustments
• Physical therapy
• Cold laser therapy
• Electrical stimulation
• Manual stretching
• Correction exercises
• Ultrasound
• Health coaching

Three Somatotypes – Body Shapes

A somatotype is the overall shape and composition of the human body. Body types based on physique have three generalized divisions:

• Endomorph
• Mesomorph
• Ectomorph

However, it is rare for someone to fall entirely into one somatotype. Individuals can have a combination of qualities from two somatotypes, like an ectomorph-endomorph hybrid or an endomorph-ectomorph, for example.

Ectomorphs

• Naturally lean with long limbs, ectomorphs typically possess a slender look no matter what type of diet.
• A lot of endurance runners and swimmers are ectomorphs.
• Ectomorphs may have a decent amount of muscle but may appear to have less muscle development because of their long limb length.
• Body fat also seems to get hidden by the long, slender figure, which means they can get away with a few extra pounds of fat.
• However, if ectomorphs do not watch their health, they can become skinny fat.

Mesomorphs

• Mesomorphs have a natural athletic look.
• They can achieve a muscular physique without really trying.
• The physiology tends to include:
• Narrow hips
• Wide back
• A large frame contributes to a muscular appearance.
• Many professional fighters, football, and basketball players are mesomorphs.

Endomorphs

• Endomorphs have a larger structure with wide hips and shoulders.
• Shorter arms and legs.
• This type of body shape is excellent for activities that require a lot of strength.
• Rugby players, strength athletes, and powerlifters are endomorphs.
• This body type is considered to be a contributing performance factor in Ironman athletes.
