I woke up yesterday and my head felt really sore but I didn't think anything of it. Later that day I was fixing my hair and noticed there's a knot on the side where it has been hurting. I had a headache all day. Today when I awoke it was still there & it's still really sore when I try to touch that side of my head. I dont remember hitting my head or anything. Do you know what this is?
