Some people get pimples on their scalps, and when these are picked, they form scabs, which get more irritated, and can scar. These are more common in people with allergies, like eczema.
These can get infected at t imes and cause a swollen gland in the back of the scalp. Shampoo with a dandruff shampoo, every other night, and use Hydrocortisone cream. Don't pick. You may need an antibiotic pill.
