Abnormally Tight, Rigid Or Tense Muscles

What Causes Tight Muscles?

Tight muscles can have various causes, ranging in severity from 'worrying' to 'serious'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose tight muscles, we could:
  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "tight muscles" as a symptom.  Here are two possibilities:
  • Chronic Fatigue-Fibromyalgia
  • Allergic Tension

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
frequent difficulty falling asleep
severe vision disturbances
frequent swollen cervical nodes
severe tinnitus
fatigue for over 3 months
high alcohol consumption
multiple swollen axillary nodes
history of tender muscles
rapid decline in speaking ability
diffuse bone pain
morning stiffness without pain
abnormal taste in mouth
... and more than 30 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of tight muscles:
Cause Probability Status
Chronic Fatigue-Fibromyalgia 91% Confirm
Allergic Tension 65% Possible
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate having muscle problems / disease, The Analyst™ will ask further questions including this one:
Do you experience tight or rigid muscles that are difficult or impossible to relax, lasting for hours or more, often accompanied by aches and pain? Do not include muscle spasms, or muscles that are well-developed through exercise.
Possible responses:
→ No / don't know
→ Sometimes a little tight
→ Often a little tight or sometimes very tight
→ Often very tight
Based on your response to this question, which may indicate slightly tight muscles, moderately tight muscles or severely tight muscles, The Analyst™ will consider possibilities such as:
