Trigger Point Injections
A trigger point injection is used to treat muscles that are in spasm, painful, or unable to relax. Trigger points in these muscles may irritate the nerves around them, causing referred pain in other areas of the body. During the procedure, a needle is inserted into the muscle and a small amount of local anesthetic is used to sedate the muscle, allowing it to relax. Trigger points usually take effect immediately and can last from hours to months.
