You gave some awesome information and help Bandersnatch_F, but why do you include anecdotal evidence of something you heard about a rugby player? It seems like peripheral information, of very little value to Mack, and quite possibly injurious. Those kinds of little tid-bits, unwittingly, can imprint themselves on a person psyche, and make them stew.
I do not mean to criticize, you are such a wealth of information, and are so very supportive. Just my own thoughts on the matter.
I've little to add Mack, you are in good hands. Personally I think you are just fine, and that the neuro will confirm this. I look forward to hearing about your undoubtedly positive results.
