Hello I found a painful lump on the bottom of my skull between right ear and middle its a bout pea size and very tender to touch, also hurts when I move my head any direction, other symptoms not sure if related or not. Severe fatigue, my coordination is off, been dropping stuff. If I stand up to fast I get dizzy, my neck under the lump is stiff and also very painful. This really worries me What could this be?
