Hi will i am not sure when i got TOS i was first diagnosed with Bilateral Carpel Tunnel in Sept 2004 then i had surgery done on both sides went back to work in May 2005. In the first week back i had the same symptoms i got off the ship the first week of July it wasn't till the end of August 05 that i was diagnosed with TOS. Had surgery done on my right side the end of August 07 and it did not work so i still have bilateral TOS.
