It may be a problem with your thoracic outlet, says Dan Ginader, a doctor of physical therapy with an emphasis on sports and dance with Mims Method PT.
Before you lose your mind, it’s not that bad. The doctor claims that the thoracic region, which is between the shoulder and the neck, is a “superhighway” of veins, arteries, and nerves in the body.
There is a lot of activity in that area since it is where your arm joins your body. According to Ginader, if you have a numb arm while sleeping.
Typing at your workstation, or even from scrolling through your phone, it may indicate that there is an issue with the outlet. But there is a simple solution.
He said on Instagram that regular numbness may result from compression of the scalene muscle, your first rib, and your pec minor muscle.
