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.
Poor mattresses: Often a cause of hip pain at night, particularly in patients who sleep on their side, or on a mattress that is either too hard or too soft for their posture type. If your spine and hips are not supported correctly as you sleep they will become strained and painful.
