Hi Aamir...

It is wise to "clear" the neck, but sounds like you have. If there is any doubt, neural tension testing can be done.

But, the specific diagnostic test for DQS is shoulder at 0, elbow at 90 degrees , thumb to ceiling. Touch tip of thumb to 5th digit and deviate ulnarly. Pain is immediate. Problem is accompanied by localized swelling and anatomically, there is adhesion of the tendon sheath to the radius when assessed surgically. Immediate relief is by surgical release of the tendon SHEATH. More conservatively.... splinting and rest, phonophoresis with cortisone or NSAID gel/cream, soft tissue release of associated muscles (not the tendon! - too inflammed). Cortison injections can be helpful if minor but should be done by specialist and minimal repeats.

It is crucial to ensure the patient is really resting... i.e. not taking hand out of splint to do housework for example!

Cheers!
