I ve just experienced a strange feeling while sitting in a chair watching tv. It was like a head rush, with the sensation of going to faint, but not passing out. It felt like a wave going up my body and to my head, and when it reached my head I felt like everything around me was muffled, and I wasn t in my body. After it left me I just felt hot and shaky, but my head went back to normal, I have fainted before and I am on blood pressure tablets and cholesterol tablets, but the last time I fainted I was told my blood pressure had hit the floor. This feeling was extremely frightening tonight and I m worried that it will happen again when I am on my own. My husband was here tonight and got me water and cooled me off.
