I had inner ear dysfunction. This caused great dizziness and actual vertigo with full on nausea. It was terrible. My Eustachian tube was crushing in on itself. An ENT helped me recover. And the trick for me was reverse ear popping. There are also nerves there as well that when they get inflamed can result in dizziness. This whole article is helpful in understanding what could be going on. https://www.mayoclinic.org/diseases-conditions/dizziness/symptoms-causes/syc-20371787 I will tell you that when I've had the episodes of vertigo and dizziness, they are debilitating for me. When I feel it coming on, I panic. I have had great anxiety over it. But I haven't had an episode now in about 4 years and hadn't had one for two years before that. So, I'm far less anxious about it now. It's natural to get panicky over something that can make you so miserable (as I get so bad I have to lay flat and do nothing until it passes and it can take 2 or 3 days). The ENT helped me tremendously.
It turns out that dehiscence is a hole in a bone that is part of the hearing/balance mechanism.
Dizzy_Girl_22, are you maybe thinking that since the gingko didn't work, that the problem is not in the inner ear? It turns out that "Ginkgo biloba extract is used clinically in the treatment of inner ear disorders such as hearing loss, vertigo, and tinnitus; however, recent evidence in support of its effectiveness is lacking." 2013 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3650561/
There is a drug called betahistine that you can ask to try, it is used far more commonly than gingko. However, is your age 22? From what I've seen, these types of 'blood flow' drugs are mainly used in people far older than that - that is, people more likely to have problems in their blood vessels.
Here is a study that tried to show that gingko is as good as betahistine, but that study failed. 2014 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4099171/ (It was sponsored by a supplement company.)
Still, it's also certainly possible that your dizziness comes from something else (like panic attacks), and not from an ear problem anyway.
Hello~Gingko is a good herb for dizziness, but, you may also have some vertebral dislocations in your neck causing the dizziness as well. I suggest seeing a good chiropractor, I see one when I am dizzy and he helps a lot. The chiropractor will take some cervical x-rays of your neck, study them and then go over the results with you. He/she will then start the treatments, if a neck issue is the problem, a few treatments should have you feeling better. Also, if the neck has some vertebrae pressing on nerves that go to the ear, you can have dizziness, again, the chiropractor will be able to help.
Hi, it seems that the 'bulb' is a sort of a bulging knot made of veins near the ear canal. The dehiscence we can say means bursting/bleeding of tissue in or near that bulb.
After only a quick look, I didn't see gingko used as a treatment. Maybe it was worth a try, rather than possibly thinking of going straight to surgery.
