"Understanding Vaccine Side Effects: Arm Pain and Remedies"
Arm pain after receiving vaccines is a common side effect caused by the vaccine entering the arm and triggering an immune response, resulting in temporary inflammation. Moving the arm can help with blood flow, but strenuous activities should be avoided. Over-the-counter pain relievers and cold compresses can also alleviate the pain and swelling. Some people may experience flu-like symptoms after getting vaccines, and there is no scientific explanation for why some individuals have more severe side effects than others. If symptoms persist for longer than a day or so, medical attention should be sought.
