you should always be concerned about chest pain but it would not be likely this would be related to your tetanus shot in any way. i don't know anything about you --- your age risk factors or anything about your medical history -- so if you are concerned enough to post you should be concerned enough to see a medical provider -- someone who has the ability to examine you and determine the reason for your chest pain and irritabiltiy.
i had a tetanus shot 4 days ago and now have chest pain and irritability. should i be concerned? . pain radiates to my upper back also.
