Hi, Tisha:
By coincidence, I've been going through my own (mild) relapse. Three days ago, I had very mild vertigo -- accompanied by not-so-mild disequilibrium -- for the first time in many years (that is, discounting a few brief episodes of vertigo that lasted only a few seconds each). It happened on Tuesday of this week; the vertigo lasted about 1-1/2 hours, and I found myself tipping over when walking around the house. Being that I had had CK fully 2-1/2 years ago, I was worried. I emailed Dr. Chang, and he replied within a few hours. He said it was not unusual to have vertigo this far out from treatment and it didn't portend I would have vertigo permanently. He said it could possibly last several weeks and I could tough it out or take steroids. He said the steroids might, "if anything" make it resolve quicker. I interpreted that as meaning it might not do anything but might help.
In the brief amount of time it took for him to reply to me, I drank a lot of water and took some natural anti-inflammatories (bromelain and curcumin). That seemed to help a lot. The vertigo went completely away and my balance improved a lot, too. Three days later, I still don't feel like I'm 100%, but I do feel much better (well enough to hike 3 miles today). I'd been taking less of the bromelain and curcumin for the past couple months -- I was getting tired of taking so many pills every day -- but have decided I should go back to taking more, as they seemed to keep my symptoms in check.
Crystal therapy: similar to kidney stones, tiny crystals can form in the semi-circular canals and throw people's balance off. A vestibular therapist will slowly rotate your head to try to get a "stuck" crystal to move. It sometimes resolves symptoms -- if indeed you have a crystal that has grown in your semi-circular canals. My guess is that your symptoms are due to your tumor. Drink plenty of water, cut back on fatty foods (except for salmon), keep your blood sugar up (don't starve yourself), avoid eating cane sugar, get plenty of rest and maybe try taking some over-the-counter anti-inflammatories (either natural supplements or ibuprofen, for example). Doing these things always makes my symptoms lessen. YMMV, so these are just suggestions of things you can try.
I hope you feel better soon!
Best wishes,
