I have mentioned it to my doctor and she said it's anxiety, but it is hard for me to believe that. Sometimes it really freaks me out and it happens randomly. Like the other day I was chatting with a friend and suddenly my head felt full of pressure and I just wanted to end the conversation. I wonder if it is caused by my allergies? Anyone else ever get this? I have had it before and my blood pressure was fine, cause I always thought it had something to do with that. Anxiety and head pressure??
