Hi there, I keep having a weird feeling on the right side of my brain. It's as if stg is rushing inside or a chill like feeling. It's not a pulsating feeling.It's kinda hard to describe and just comes and goes all day long. I have been experiencing it for a while now. Could it be stg serious? Like do I need to take an MRI or other tests? What do u think this is or is this normal? Thanks in advance 🙏
