Why do pimples burn?

Pimples can burn due to inflammation caused by the body's immune response to bacteria and excess oil in the clogged pores. This inflammation leads to increased sensitivity in the affected area, which can manifest as a burning sensation. Additionally, the presence of certain irritants or harsh skincare products can exacerbate this feeling. Overall, the combination of irritation, swelling, and sensitivity contributes to the burning sensation associated with pimples.
