I have to deal with this a lot with my health, I have something they don't even have a name for but basically I have a headache every day. Some days are better than others, but some come with huge vertigo issues and I'm stuck.
I agree with the others, you should definitely talk to your doctor about it (I am NOT trained in health care at all, I am only offering advice as I've been to many many doctors in the last almost ten years), however, I do have something that might help until you get to them or if they just tell you it's "something you have to deal with."
Basically what I'm offering is a "recalibration' so to speak. There are a few stages, do what you CAN without risk of injury, there's no shame in starting small.
Start in your chair, preferably one that spins. Start one way and stare at a specific point on a wall, swivel your chair 180 (think from front to back for those like me who aren't sure of degrees..) and focus on a point on that wall. Your head will spin, you'll feel sea sick. Wait until it calms down, and spin again, forcing your eyes to focus. This will 'retrain' your brain to think in these terms and it will get used to the motion. By the time you've done this a few times, it should be easier and easier. If it doesn't get easier, stop...
If you can do that with ease, do it by standing next to a wall, putting one hand on the wall and doing the same only spinning so that your other hand is on the wall, this will insure that you can catch yourself if it's too much. Do the same motion over and over until your body adjusts.
Then of course, if you can do all that, do without the wall and spin as much as you can until you get used to it. This has helped me and I hope it does for you, vertigo is NOT fun and I'm sorry you're going through it!
