Well, you need to have that scan and if it's a 40-minute jobbie, it's better than the type of scan that I suspect most of us T sufferers will have been offered/given, which lasts about 15 mins. Sounds like you may be scheduled for an MRI/venogram, which is the gold standard to look for blood flow anomalies as well as brain/neuromas.
I suggest you take some ear foam protectors with you (Boots, about £3). These squish right into your ears and are good at deadening sound. If you don't get on with foam plugs, try the swimmer's gold standard ear plugs, i.e. Macks aquablock ear plugs. They are on Amazon for again about £3. They are mouldable to one's particular ears and block everything out. I've used both, the foam for dry plugging, Macks for swimming.
