Hi ,
Yes , it can be very much related to repetitive uses.

Lawyers, students, nurses, musicians, you name it -anyone that is in static {non active} & desk type postures for long hours & years could be at risk.

Other possible factors-
Hyper mobility
previous whiplash,Car accidents
previous RSI (repetitive stress injuries)
upper body hits, sports injuries, falls


9 months after surgery can be about the time frame that any scar tissue adhesion problems can show up.

Seems surgery works well for some but only partially for others.

Keep looking for better ergonomics and posture helps - move around as much as you can often.
see many of our other recent threads & posts here on the forum. And the useful sticky threads up above.

get Dragon or use your speech/voice recognition software if your computer has it built in already, Vista & Win7 have it as well as Mac.

My usual suggestion is to get a comprehensive evaluation from an expert /advanced PT or a very good DC.
They should also be able to tell if something else is going on that the surgery didn't even address.

There are things that can be done if it is a scar tissue/adhesion causing some of these problems - the thing is to be proactive on therapies and not let it get to a chronic stage.

Don't assume Drs know it all or that pain meds will heal you.

You're going to have to learn about the anatomy of the upper body & use you own logic to find the best things for you.

Please do read the recent threads as many thoughts and ideas are posted
