Hi,I am Dr. Amitkumar Sharma (Internal Medicine Specialist). I will be looking into your question and guiding you through the process. Please write your question below.
I got a tetanus shot on Thursday, my arm is very sore which I know is normal, but it is red and has a knot in the injection site which has gotten a bit bigger and this morning I noticed a squishy lump on my collar bone, same side where injection was given is this also a side affect?
