A muscle knot is the lay term for what are also known as trigger points, sometimes abbreviated as TrP. These are sensitive points all over your body, but mostly on the back and neck that are particularly sensitive to irritation.
If muscle knots are chronic or donât respond to massage, it may be time to see your doctor. Injections of lidocaine or corticosteroids to the knot and surrounding muscle tissues induce the fibers to relax. This option is also good for dealing with trigger points that occur after an accident or injury to the muscle.
