Morning stiffness can have various causes, ranging in severity from 'needs attention' 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 morning stiffness, we could:
osteoarthritis
frequent swollen axillary nodes
very great unexplained weight loss
scleroderma
major pain in cold/cool/damp weather
joint pain/swelling/stiffness
brittle fingernails
daily morning stiffness
swollen inguinal nodes
hot flashes between period
metallic taste in mouth
occasional 'chills'| Cause | Probability | Status |
|---|---|---|
| Scleroderma | 95% | Confirm |
| Osteoarthritis | 28% | Unlikely |
| Psoriatic Arthritis | 26% | Unlikely |
| Lupus (SLE) | 4% | Ruled out |
| Juvenile Rheumatoid Arthritis | 3% | Ruled out |
| Rheumatoid Arthritis | 0% | Ruled out |
| Chronic Fatigue-Fibromyalgia | 0% | Ruled out |
| Ankylosing Spondylitis | 0% | Ruled out |
