Numbness or tingling in the arms can be a warning sign of thoracic outlet syndrome. This condition occurs when nerves or blood vessels are compressed, leading to restricted circulation and nerve function. Thoracic outlet symptoms in CA often include arm weakness, swelling, and persistent pain, especially when lifting objects. At Encino Vascular Institute, we specialize in identifying and managing these symptoms to prevent worsening conditions. Early diagnosis and personalized treatment can significantly improve mobility and reduce discomfort. If you frequently experience arm numbness, seeking professional evaluation is crucial for timely intervention and relief.
