If its a large bump you might have missed your vein and injected in your tissue. Usually your body will absorb this over time but if it doesnt go away in about a week or so you might be developing a cyst. Then its time to see a doctor. Or its just the spot where you injected, its gonna leave a mark on the skin.
A lump usually refers to a mass or swelling beneath the skin, commonly due to tissue growth or inflammation. On the other hand, a bump is a raised area on the skin that can be caused by various factors such as injury or insect bites. Essentially, a lump is a more generalized term for any abnormal growth or swelling, while a bump is more specific to a raised area on the skin.
