Is nausea and dizziness common?

I got tinnitus four weeks ago and this week I started having nausea and dizziness. Especially with sudden movements. Is it common with tinnitus? Also, caffeine makes it worse. I’m not off balance or anything. I have history of migraines and I also got couple of migraines in last week. I have an appointment with ENT in three weeks. I just wanted to ask the community if anyone else had these symptoms.
