Hi, for 3 days I ve had pressure and tingling in my forehead on the left side, and behind left eye. Also feeling a bit like I might throw up and feeling foggy. My teeth tingle and sometimes my lips feel puffy but they aren t. This seems to be happening every few weeks on and off. I suffer from migraines but this doesn t feel the same as they usually do when I have them. I ve had a ct scan that showed nothing. My GP doesn t seem to be concerned, but it s making it hard to get through the day. Have you got any idea what might be causing this.
