Hi and welcome to the forum
I am 17 mos. post op and I very very little to no tearing in my eye on my AN side. There are quite a few people on the forum with this same problem, all with varying degrees of dryness. If you haven't seen an eye doctor yet you probably should, just to make sure you are keeping your eye lubricated enough to protect your cornea. Some people say the dryness improves, but I haven't seen any improvement in mine yet, still hoping. As for the taste thing, my ttongue was actually the only place I had any symptoms before I was diagnosed. It was numb and tingly and things tasted funny. Numbness and tingling are gone, but I have very strong taste sensations on that side especially when I eat salty foods. The saltiness stays with me for hours, but there are worse things in life,
The balance issue you describe is what I believe other forumites call "wonky head". It does get better as your good side learns to compensate. Vestibular therapy is a great way to speed up the process, and Clarice mentioned some great exercises you can do by yourself. The only time I really get that feeling anymore is when I am not out being active enough and my body gets lazy and doesn't compensate as well. You are still very early into your recovery, so remember to be patient and allow yourself to rest as needed. You sound like you are doing well so just keep on doing what you're doing
I am not familiar with the surgical approach you had, could you tell me more about it?
