these are symptoms that my fiance experienced before he was diagnosed with GBM grade iv...
Weeks before he went into coma, he kept saying if I pass out tell the doctors my brain is bleeding....
he always laughed it off and when I asked if he was seriously he always said he was kidding. But, he wasn't...he did have serious and correct body intelligence/intuition.
I hope your MRI gives you resolution...I wish you healing.
