Likewise, existing and known diseases are an important starting point to provide the physician with an initial indication of the cause of numbness.
During a physical examination, the doctor will try to delimit the area affected by numbness as accurately as possible. This can help you locate possible nerve damage. Own reflexes are checked to determine neurological deficits: hearing, sight, sense of balance and the state of consciousness.
If numbness lasts for a prolonged period, you must consult your doctor immediately. Go to hospital urgently, if you have any symptoms at the following:
- Difficulty moving or walking
- Sphincter control is lost
- There are visual disturbances or difficulty speaking normally
- Agitation or confusion of thought
- Loss of consciousness
- Numbness linked to a rash on the skin
