Head symptoms?!?!?

[mkgirl01]

So the back of my neck often feels weird??? Sometimes it feels like my heads gonna fall off or my head is full of air... It feels heavy but light and I get a weird feeling in the back of my neck.... What is it

[petrified]

Not sure but I get that, sometimes it's just one side that feels heavier to me as well. It's very strange I think it's over tiredness with me sometimes
