I had a tetnus shot on Monday and by Wednesday evening I noticed a lump on my left collar bone. It moves around and is sore when I touch it. Is this just from my shot. How long before it goes away if it is.
Sometimes people do experience soreness and some even have a lump at the site of an injection. It can occur with a tetanus shot or other vaccination as well. The lump and soreness would be where you got the shot. Both should go away in a few days. It sounds like the tetanus (Tdap) shot was administered high on your upper left arm if thats where the pain and lump are.
It could possibly be a swollen lymph node from the vaccine, I suppose. Or it could be unrelated. Just keep an eye on it. If it is a swollen lymph node, though, poking at it will make it hard for the swelling to go down, so try not to touch it.
