The cause of your muscle pain or spasms maybe one or more trigger points. Trigger points are specific sites on the muscles that cause pain (both locally and throughout the back) when pressure is applied to them. Trigger points are believed to occur due to excessive physical activity, fatigue or trauma. This injection is done in the comfort of the physician’s office. The physician will feel and stretch the muscle to find the trigger point. The physician will then do a series of injections with various medications to best relieve the pain. This type of injection may help you increase movement and may help the muscle heal.
The sympathetic nervous system is a network of nerves throughout your body. The nerves branch from your spine and control some body functions, such as the closing of blood vessels. A problem with these nerves can affect blood flow and cause symptoms in the hands or feet. They may hurt, burn, feel cold, or be tender to touch.
The sympathetic nervous system is controlled by bunches of nerves called ganglions. One large ganglion, called the stellate ganglion, helps control nerves in the upper body. In the lower body, nerves are controlled by several ganglions that make up the sympathetic chain.
