what does a muscle knot feel like
A trigger point is simply a small contraction knot in muscle. This knot feels like a pea buried deep in the muscle, and can feel as big as a thumb. It maintains a hard contraction on the muscle fibres connected to it, thus causing a tight band that can also be felt in the muscle.
These are the most common type of headache. They can feel like pressing or a tight band around your head. Experts originally called it a tension headache because they thought that the muscles were tight or tense, says Jason Rosenberg, MD, director of Johns Hopkins Headache Center. It turned out that no study could prove that, and the muscles are actually not tight.. Experts now call them tension-type headaches.
