I doubt that your acoustic neuroma could cause the problem you re indicating. Your symptoms are more consistent with what could be referred to as a transient ischemic attack or TIA. Some people may use ministroke which I find very misleading since this is very inaccurate and not standardized. I think that you should make an appointment to either see your primary doctor or a neurologist as soon as possible and discuss what happened. It will be to their discretion as to how you should proceed but a warning like this (if it was a TIA) should not be ignored. It s a heads up to something more dramatic which could be avoided if you could know more information. Immediately stop smoking cigarettes or engaging in lifestyle habits of risk, keep yourself well hydrated at all times, if you are diabetic make sure your control is optimum and don t be lax about following the strictest instructions by your doctor regarding fingersticks, sliding scale insulin injections, diet, and exercise. All the best.
