hello, I am 4 months pregnant, I got my first tetanus injection 4 days ago, but it still pains a lot. what should I do?

A. You should get a check with your doctor because it should not be paining I am anyway tetnus does not pain for a longer duration like this so maybe there is some problem better get a check with your doctor prior to that you can do a cold sponging or you can keep ice pack or cold pack that should be helpful
