It could also be a wart, quite common. You could try putting some type of topical astringent on it to see if it reduces the size. If it’s more like a zit, that will tend to reduce it’s size or it may even go away on it’s own as the body reabsorbs the pus.
If it’s something like an ingrown hair it should likely get larger and more sore until it eventually ruptures. If it’s a wart it will probably maintain it’s size or get harder.
