See this boring little injury here?
It is called finger-bump, writer’s callous or nerd's bump — and for the right reasons.
It isn’t particularly painful or noticeable. In fact, I didn’t discern this on my finger until it began to cause obstruction in holding a pen. On a quick search, it proved to be a writer’s bump.
My days are full of writing by conventional tools, and that pretty much explained it.
When we hold a writing tool like a pen for long, it rubs against the middle finger. The bump, made up of a cluster of dead cells, is essentially a defence mechanism to protect the underlying area of the skin. It prevents any kinds of irritation or infection.
There are various ways we could use to remove it.
One such way is to soak your finger in warm water for a few minutes. Then gently rub a cloth or a pumice stone to exfoliate the dead skin cells. Do never cut off the callus as it could lead to an infection
.One can also apply oils or moisturisers to speed up the process.
As prevention, you can use finger protectors or wear gloves to end contact from the tool. Using pencil grips is another method to minimize friction. Taking a break from writing, if feasible, can also cease it.
