Tingling extremities can have various causes, ranging in severity from 'troubling' to 'life-threatening'. 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 tingling extremities, we could:
|Vitamin B12 Need||13%||Unlikely|
|Magnesium Need||3%||Ruled out|
|Guillain-Barre Syndrome||1%||Ruled out|
|Phosphorus Deficiency||1%||Ruled out|
|Silicone Disease||0%||Ruled out|
Do you have any numbness, burning, or tingling of the extremities (toes or fingers)?
Possible responses:→ No / don't know
→ Yes, a little on one hand or foot only
→ Yes, severe on one hand or foot only
→ Yes, a little on two or more hands/feet
→ Yes, severe on two or more hands/feet
Dehydration can cause an electrolyte imbalance. Sodium is an electrolyte involved in nerve signaling, so an imbalance can cause numbness, burning, or tingling sensations.
Symptoms generally begin in the patient's feet, hands or face, spread to the legs or arms, and increase in intensity as they move towards the center of the body. They generally appear on both left and right sides of the body. However, GBS is unpredictable, and cases have been reported in which this "glove and stocking" pattern is not followed. Instead, motor symptoms or disruptions in the autonomous system may be observed. GBS may also affect an arm or a leg alone, without spreading to the rest of the body.
If vitamin B12 deficiency becomes pronounced, the nervous system can be affected, causing progressive peripheral neuropathy (tingling of the fingers and toes), muscle weakness, staggering, tenderness in the calves, confusion.
