I have been on my feet all day working and as soon as I've sat down my head feels so heavy and the pressure is really strong coming down my forehead. I also feel like I need to pop my ears, like my hearing isn't what it normally is. I find with this dizziness and head pressure it is worse when walking around. Now I have rested its all hit me at once more than normal when I can restrict how much I move about? Does this make sense to anyone????
