This morning I notice my neck was very swollenad na noticeable big lump like nott very puffy like when I swallow it hurts alittle my muscles kinf of push against it I thaught my throat was sore but it is the nott that is sore specially when you touch it or my muscle push against it from inside. the swelling goes up an down all through the day. Can some doctor or heath profession tell me what that might be or what should I do.
