Loss of sensation can have various causes, just like most other symptoms. 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 loss of sensation, we could:
Are there any areas of your body where you have experienced reduction in your sense of touch (numbness), or where you are unable to feel anything at all?
Possible responses:
→ No / don't know→ Yes, sometimes in one particular area → Yes, usually or always in one particular area → Yes, sometimes in more than one area → Yes, usually or always in more than one area |
