Can a staph infection cause your forehead to swell?

Yes, a staph infection can cause your forehead to swell. Staph infections are caused by bacteria that can enter the body through a cut or scrape, or through a weakened immune system. When these bacteria enter the body, they can cause an infection that leads to swelling, redness, and pain in the affected area. If the infection is severe, it can also spread to other parts of the body and cause more serious health problems.
