Uhm, I'm 20 years old and to the extent of my knowledge I've never had any problems with anxiety but today, I woke up generally fine. Went through my morning routine then around noon something changed and my head has been feeling like I'm on an airplane--like my ears need to pop, there's a lot of pressure but it's not painful just off-putting. I can hear my pulse rapidly beating it lasts for about 5-10 seconds then it stops and I get this hot-flash like feeling down my back, legs, and arms into my hands which lasts for about 3 seconds then it all goes away for about 5 minutes then the process starts all over again. My nose isn't stuffy, my head doesn't hurt, I'm pretty sure I don't have a fever. My husband doesn't seem concerned but my step mother thinks that it could be anxiety. Please help me out. Tell me if these are the symptoms or if it's something else entirely.
Much appreciation for any/all help, thanks.
