Subacromial Bursitis

Explanation of Diagnosis

Subacromial bursitis means the bursa (a small fluid-filled cushion) above the shoulder joint has become irritated and inflamed. This bursa helps reduce friction as the rotator cuff tendons move under the shoulder’s bony arch. It often happens after repetitive overhead reaching, lifting, or a direct bump, and sometimes develops gradually with chronic strain. Common symptoms include pain on the outer (side) shoulder, tenderness, stiffness, and pain that may worsen when you lift your arm away from your body or reach overhead.

Specific Work Modifications

• Place frequently used items between waist and shoulder height to reduce overhead reaching.
• Use a step stool so you can bring your work up to your arm rather than reaching up with your shoulder.
• Take short “reach breaks” every 20 to 30 minutes to change positions and avoid repetitive arm lifting.
• Limit repetitive lifting, carrying, or scrubbing with the arm held out to the side; keep loads close to your body.
• Use assistive tools like a long-handled reacher, light cart, or vacuum attachment to reduce shoulder stress.
• If you work with your arm elevated, adjust your workstation so your work surface is closer to your body.

Specific Activity Modifications

• Avoid activities that repeatedly raise your arm overhead (throwing, serving, overhead presses, and most swim strokes in the early phase).
• Reduce or pause behind-the-back motions (certain yoga stretches, reaching for back pockets, or fastening a bra strap).
• Switch to lower-irritation movement like walking, gentle cycling with good posture, and light range-of-motion activities.
• Choose lighter weights and avoid motions that trigger sharp shoulder pain, especially slow controlled lowering after lifting.
• Modify household chores by using both arms, keeping elbows closer to your sides, and breaking tasks into shorter sets.

Recommended Supplements

• Fish oil (omega-3), about 1 to 2 grams per day of combined EPA and DHA, may help support a more balanced inflammatory response.
• Curcumin (turmeric extract), about 500 to 1,000 mg per day with food, may help some people with pain and inflammation.
• Vitamin D3, about 1,000 to 2,000 IU per day if you are often low or have been found deficient, supports musculoskeletal health.
• Collagen peptides, about 10 grams per day, may support tendon and soft-tissue remodeling when paired with appropriate loading.

Recommended Nutrition and Hydration

Diet Recommendations

• Aim for adequate protein at meals to support tissue repair (for example, include a protein source at each meal).
• Choose an “anti-inflammatory style” pattern with fruits, vegetables, beans, nuts, and olive oil most days.
• Include omega-3-rich foods such as salmon, sardines, chia, or ground flaxseed if you tolerate them.
• Limit alcohol and reduce ultra-processed foods and sugary drinks, especially during flare-ups.

Hydration Tips

• Drink water regularly through the day rather than only when you feel thirsty.
• If you sweat a lot or exercise, include additional fluids and consider an electrolyte-containing drink as needed.

Home Exercise Prescription

Do these exercises about 4 to 6 days per week, keeping movements in a comfortable, pain-guided range.

1. Pendulum (shoulder swing): Lean forward with your other arm supported, let the sore arm hang loose, and make small gentle circles or side-to-side swings for 30 to 60 seconds.
2. Scapular setting (shoulder blade squeezes): Sit or stand tall and gently pull your shoulder blades down and back without shrugging; hold 5 seconds, repeat 10 times.
3. Table slides (forward reach): Use a table or counter to slide your forearm forward until you feel mild stretch or discomfort (not sharp pain); hold 5 seconds, repeat 10 times.
4. Wall walk (controlled flexion): Stand facing a wall and “walk” your fingers up to the highest comfortable level; return slowly, repeat 8 to 10 times.
5. Isometric external rotation: Stand with your elbow tucked at your side and a towel between your forearm and your body; gently push outward into your towel without moving your arm, hold 5 seconds, repeat 10 times.

Stop if you get sharp, rapidly worsening pain, new numbness/tingling, or a sudden loss of strength.
