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.
The more common causes of pain that tends to worsen or start at night includes 1  : Gastritis. Inflammation of the stomach wall that is more commonly caused by H.pylori infection or NSAIDs. 2  Peptic ulcers. Open sores in the stomach and/or duodenum (first part of the small intestine). 3  Acid reflux.
