Im experiencing something new... I had a horrible headache the other day but after i slept it went away mostly. Now im left with head pressure and a weird feeling that feels like the start of a head rush.. Its so hard to explain. It happens at random times but its like a tightening that comes from back of my head to my temples and behind me ears, it even makes the bridge of my nose feel tight for a second. It goes away and then comes back. I hate it and now its got me worrying about yet another thing. I hate this pressure in my head. I also feel nauseous. Has anyone experienced this? Its got me so uptight wondering when its gonna happen again.
