Hi Kathy,
I wouldn't expect your symptoms to resolve so soon after treatment. After all the AN is still there, and still pressing on your trigeminal nerve (which is causing the numb tongue), vestibular nerve, etc. I am now a bit more than a year post-GK, and my numbness is still there - I don't expect it to go away either knowing the nature of the treatment, just hoping that it won't get any worse.
My understanding is that if you don't notice anything different, this is good news. I was worried that the treatment hadn't worked, because I didn't experience any symptoms, but I was told that if everything is going well (i.e. no swelling etc), then I shouldn't be feeling anything out of the ordinary. They were right, since both my 6 month and 12 month MRI showed necrosis and stable size.
You are still early in your journey post-treatment, so hang in there. Be aware of any increased diziness when turning fast your head from one side to another, and of any sudden hearing loss or sudden onset of any other symptoms. Report anything like that right away to your doctors. In the meantime, no change and no news is good news. Vestibular therapy has helped quite a few people here with their balance issues and I found that warm compresses and ibuprophen help ease the odd sensations due to the trigeminal nerve irritation.
