Causes of Vertigo. Vertigo is often caused by an inner ear problem. Some of the most common causes include: BPPV. These initials stand for benign paroxysmal positional vertigo. BPPV occurs when tiny calcium particles (canaliths) clump up in canals of the inner ear.
I think the pain is worse at night because of the activity during the day. I do experience pain at night (and throughout the day off & on). It makes it hard to go to sleep at night plus in the middle of the night the pain wakes me up.
Toothache that gets worse at night may be due to several tooth or dental problems. Sinuses can result in dull throbbing tooth pain especially at night. This is due to trapped mucous on lying down thus, severe toothache.
