This is the most common cause of nail pops and it’s fully beauty. There are no structural issues to fret about, and repair is pretty simple.
Smooth over indentations with somewhat joint compound—a quarter-sized glob should fill most nail and screw indentions. Apply with a putty knife, then clean away any extra. Let the compound dry no less than 24 hours, and then apply one more thin coat of joint compound with the putty knife. When that dries, sand over the compound with a drywall sanding sponge, after which roll on a brand new coat of paint.
This can cause individual nails to move, and when a nail holding drywall moves, it loosens the joint compound masking the nail. The result is a tiny bulge on the wall surface or, in some cases, a visible nail head if the drywall compound comes free and falls away.

Cover the whole patch space with a coat of primer, using a paintbrush. Apply two or extra coats of paint to match the encircling space, as wanted. Alternatively, if the wall or ceiling might use a brand new paint job, this is a nice time to color the entire thing, which will assist disguise the patch. Cover the drywall tape with a skinny layer of drywall joint compound, utilizing a 6-inch drywall knife.
Lumber used to construct homes could include moisture, which is often absorbed from humidity in the air while lumber is stored in open-air warehouses. After development, because the wood slowly dries, the studs could shift or twist barely.
