I absolutely recommend further testing, with a definitive consultation with a Neurologist to do the specialized testing and recommended treatment. I also recommend immediate treatment with occupational, physical and speech therapist as to maintain if not improve the deficits you describe early. Your Primary Care Physician and or Neurologist will be able to refer you to these forms of therapy, and such may indeed be covered by insurance or your carrier based on what you described to me; but I would look into it nonetheless. In summary, the symptoms you are experiencing can be temporary and you can indeed possibly return to normalcy with no intervention; depending on the particulars of the situation, which sitting here responding to your case I cannot access at the moment. Nevertheless, I personally would not risk patiently waiting, and would want to get such symptoms checked out and dealt with early as to not ensure permanent issues. Therefore my recommendation is to stay healthy, keep practicing your speech, and challenge your cognition with mental tests as self therapy (the more you challenge your brain the quicker it heals), and at earliest convenience schedule an appointment with a Neurologist. :) I hope my recommendation has helped.
