Welcome to Just Answer. I am an Adult Neurologist and was contacted to answer your question.
hello. waiting for you to come online
as you are offline, I will leave you a statement, please get back to me if you have questions
I would say from your lengthy description, and your ability to look at yourself and admit that you are scared
that this is most likely a case of health anxiety, and most if not all of your symptoms can be
linked to that possibility. The diffuse twitches in a young athletic male with good muscle tone is benight
benign fasciculation syndrome at an incidence of 1:80 as opposed to ALS at an incidence of 1:200000
your muscle spasm and increased tone which initially responded to chiropractic manipulation is
part of BFS commonly, and the tingling you feel could be part of increased muscle tone in the spine.
This happens as the small nerve fibers are pinched by the muscles as they exit the spine.
I would suggest you consider trying the muscle relaxant.
that would also give you some indication of the effect of this increased muscle tone on your tingling response
please get back to me if you have questions I could answer, or rate my service if satisfied. Dr Frank T
