A trigger point is a tender point in a muscle which when pressed causes pain.
In its active state, a normal muscle is supposed to contract and relax. A trigger point is formed when the muscle fails to relax and a knot or tight ropey band of muscle is formed.
The trigger point can trap or irritate the surrounding nerves and cause pain to be felt in another part of the body.
A trigger point injection is an injection of local anaesthetic and steroid into a trigger point.
Trigger-point injections (TPI) have been shown to be one of the most effective treatment modalities to inactivate trigger points and provide prompt relief of symptoms.
I am having my first dose of these a week on Tuesday so I will diary how I get on.
