I remember this happening when I was younger and it's been more frequent, it's so hard to explain and describe!!!! It sounds like pop rocks in my head or when you open a can of soda and it makes that fizzy noise... I'm not sure if it has to do with my ears or my head but it freaks me out! Everyone I ask has no idea what I'm talking about makes me feel kinda crazy! Anyone know what I'm talking about? My vision isn't weird or my head doesn't hurt so idk what's going on
