I received a tetanus shot yesterday and today noticed a lump under my left arm pit. I feel fine, except for some drowsiness, which I m assuming is my allergies. I m 23, male, quitting smoking but I m wondering if receiving a tetanus shot cause lymph node swelling? I already scheduled an appointment with my doctor tomorrow to be sure
Hello. Thank you for writing us here. Well for what you took the tetanus shot by the way? Because of come contaminated injury or something like that? If yes, its most likely to be because of some minor infection which your lymph node Chat Doctor.  It would be alright in 8 to 10 days and for your own satisfaction, you can ask your doctor for ultrasound of your lymph node. There's nothing to be worried about okay? After TT shot to some people develop minor inflammation causing the lymph nodes to swell. Best regards,
