Can a flu shot or tetanus shot cause shoulder impingement syndrome? Yes. Shoulder impingement syndrome can occur as a form of SIRVA (Shoulder Injury Related to Vaccine Administration) when a vaccine is injected too high or too deep into the shoulder, causing inflammation that narrows the space around the rotator cuff tendons and leads to pain and restricted movement.
If you’re experiencing persistent shoulder pain after a flu shot or tetanus vaccine, you may be dealing with shoulder impingement syndrome — a form of SIRVA (Shoulder Injury Related to Vaccine Administration).
What Is Shoulder Impingement Syndrome?
Shoulder impingement syndrome occurs when the rotator cuff tendons become compressed as they pass through the narrow space beneath the acromion (the top part of the shoulder blade). This compression can cause pain, inflammation, reduced range of motion, and weakness.
How a Vaccine Can Cause Impingement (Anatomical Explanation)
A flu or tetanus shot should be administered into the deltoid muscle. If the injection is given too high or too deep, the needle can contact structures such as the bursa, rotator cuff tendons, or joint capsule. This can trigger inflammation and swelling, reducing the already tight space under the acromion. As the space narrows, the tendons become pinched, resulting in impingement and pain.
Legal Explanation: Do You Have a VICP Claim?
The National Vaccine Injury Compensation Program (VICP) provides compensation to individuals injured by certain vaccines, including flu and tetanus shots. Eligibility depends on symptom onset, persistence, and medical diagnosis.
