A recent post on the Pennsylvania Workers' Compensation Lawyer Blog concerns an ongoing study to determine whether an injection of BOTOX may provide relief from the symptoms of thoracic outlet syndrome. The study is scheduled to be completed by August 2009.

The symptoms of thoracic outlet syndrome include hands that feel cool and tire easily, aching pain in the neck, shoulder, arm, or hand, and difficulty performing overhead activities. Although thoracic outlet syndrome is frequently caused by injury, it may also result from disease or congenital abnormality.

It is more common in women than in men, and is often accompanied by psychological changes. However, it is not known whether these psychological changes precede the condition or result from it.
