Yesterday My Scalp Started Itching In One Spot Then Different

Yesterday my scalp started itching in one spot then different parts of head, itching like crazy. It woke me up twice last night. I put coconut oil on my scalp today and it is itching terribly again right now. I feel bumps on scalp and it itches around these spots.I also have a swelling in spots. A large area under my ear and down my neck is swollen and a pea size lump behind my ear lobe. My right ear is red, hot and swollen
