hi,
muscle overuse....drive too long.....equals muscle inflammation or use of accessory muscles not normally used due to the overuse.....inflammation leads to compression of nerves and vessels which causes tos symptoms!!!!!!!!!!!!!!!!!

tos could be transiant or intermittant or come back if the same conditions come back to cause the pain.

Sorry to see you return.....I too was pain free for only six months post op but can relate to the pain free then back to hell.....the tos symptoms may well be due to the drive.......hope you get the help you need and WELCOME to our little oasis (again)

love and hugs,
Victoria
