My arm started hurting after receiving the COVID-19 vaccine last year, and it's still painful now. What could be causing persistent arm pain six months after getting the COVID-19 vaccine, and what should I do?

In general, if the arm has been painful for six months after receiving a COVID-19 vaccine, it may be due to stimulation of the muscle nerves in the arm during injection. It is also possible that poor absorption of the vaccine by the muscle tissue led to inflammation or infection at the injection site. Patients experiencing this condition should seek timely medical evaluation and appropriate treatment. Applying warm compresses with a hot towel to the affected area regularly may help alleviate pain symptoms.
