Ears ringing
I took this online hertz test cause I was bored, and apparently I can hear up to 18 kHz. But that's not the problem. After I took the test, the ringing in my ears won't stop and I hear this high-pitched noise from my laptop. Its been ringing for about an hour now and still hasn't stoped. Now im getting a head-ache aswell. Is that bad? This also happened when I took an MRI of my brain, except the pain in my head was worse. I could barely walk then. Is there something wrong with me?
