its very rare for a technician to say anything. I have a lot of the same issues as you except mine was caused by a brain injury. nothing shows but all of the symptoms are there. a visual test finally confirmed brain damage. please do not use your strength worrying about the results. that day will come before you blink your eyes. I have tried to stop worrying about the symtpoms getting worse and god knows what else. it is not worth it in the end. i'm so glad I found this board and have people to talk with. good luck and let us know what happened.
