Muscle knot is the collective term for a condition called myofascial trigger points; there is a specific area of a muscle that causes pain or twitching. Touching the area results in pain, often radiating from the problem area. Sometimes a palpable lump, or “knot,” can be felt in the tissue. Mobility can decrease in muscles with a knot. There may be a painful tightness in the area and a slight warmth to the skin. 

Identifying these problem areas rely on the patient describing their pain and a doctor or specialised physiotherapist using their hands to locate the problem.  Always discuss matters with your doctor or physiotherapist. They will be able to recommend a treatment plan based on you and your issues.
