I have had recurrent migraines with dizziness and tinnitus in my left ear for 3 months. No obvious sign of infection in the ear but I feel pressure in there all the time. I have now had 2 bouts of tonsillitis in the last 5 weeks treated with antibiotics. I finished the second course on Thurs and today I can already feel my throat getting sore and glands up again. I am due to have an MRI on Monday but ENT have said this will most likely not show anything. My normal migraine preventatives are not working when they normally do and I m now feeling pretty desperate. Is the MRI likely to identify where the problem is and signpost for some effective treatment? Or is it only going to rule out anything really serious?
