Hello everyone

i am new here and just wanted some advice, in march i had the most severe migraine, flashing lights, vomitting and the pain was like nothing i have ever felt before, this lasted 24 hours but came out of nowhere, since then i have had near constant dull head pain but not every day, palsating whoosing in my ear, vision issues, slight blance problem (feel like im going to the side). So yesterday i decieded to speak to my GP who said i would have to go to the surgery to be examined... 10 mins later another GP rang me to say actually we are sending you for an urgent 2WW MRI scan... i am now so worried this may not be migraine? Has anyone else had this problem? And what was the outcome?  TIA.
