Flu shot season is here – if you recently received a flu shot and have shoulder pain, you may be wondering how long will the pain last? Shoulder pain and soreness at the injection site immediately following a flu shot is very common and should subside within a few days. But what happens if it doesn’t? Shoulder pain that worsens or does not improve within the first few days following a flu shot may indicate a more serious condition known as SIRVA, or Shoulder Injury Related to Vaccine Administration. Some common symptoms of SIRVA include pain at the injection site, soreness, stiffness, weakness, and limited range of motion. If you have shoulder pain following the administration of a vaccine such as a flu shot, you should get medical treatment as soon as possible.
