3. Weak grip happens because of an injury is a symptom to watch out for in thoracic outlet syndrome.
The reason why a person could have a weak grip is by repetitive movements that over time has caused injury. For example, a person who works in a warehouse and has to lift on heavy boxes, may hurt his or her hand. In the process, their ability to grip things may become limited. They may need assistance when lifting heavy boxes.
When this happens nerves in the hands are pressed together and causing the person to be unable to have a tight grip. It’s almost as if arthritis has formed in the person’s hands. With arthritis, there is pain and swelling. A person is restricted to the things that he or she is able to do, such as gardening. Gripping gardening tools will become a chore in itself when thoracic outlet syndrome is present.
