Tingling in the arm, neck and shoulder pain, heaviness, or weakness when lifting your arm may be signs of Thoracic Outlet Syndrome, a condition where nerves and blood vessels are compressed between the neck, collarbone, and shoulder—often caused by poor posture, tight muscles, and prolonged sitting, and commonly mistaken for simple neck or shoulder pain. #thoracicoutletsyndrome #reelsviral #trendingvideo #PhysicalTherapy | Physical Therapy Session
