Hi cargoshort, I tried to post a few minutes ago, i wrote a long post. It didnt go thru. Yes i go to a chiro all the time for it. I do know of a good site on it. Called upcspine.com.
Many times, a person thinks the sinuses, or their ears are the cause. Sometimes its the neck and OR jaw.....which are very close to the ears. Now you have a tooth thing going on there? Thats could have the entire area messed up and creating the dizziness and sinus problems. PLEASEEEEEE get it fixed. For me? My problems started with a tooth gone haywire.
I loved the other persons thoughts to, on the low oxygen. could be that. cindy
