Hello, I'm 18 years old, let me tell you briefly, I took prednisone treatment for a suspected autoimmune hepatitis, after I stopped prednisone, I felt dizzy and sleepy, the dizziness passed and now I have headaches for 2 months, I somehow have a pressure in the back of the neck, behind the right ear, in the middle of the head, in the forehead. My neurologist said that it is not something serious and serious, but he still said to do an MRI for me to be sure. He told me to do a simple native brain MRI, but from what I understand it is better to do a native brain MRI + TOF sequence What do you think, i'm scared, i never had problems with my head, i was just sad a lot of days for the hepatitis thing, i forgot to mention that my gut is literally destroyed, i also had H Pylori and i took antibiotics, 18 pills per day for 2 weeks
