What to expect at your health care provider's office
Your health care provider will take a medical history and perform a physical examination, with careful evaluation of your nervous system.
Medical history questions may include the following:
What part or parts of your body have numbness or tingling? The trunk? Your legs or feet? Your arms, hands, or fingers?
Which side of your body is involved?
Which aspect of the specific body part? For example, is your inner thigh, calf, or foot affected? Your palm, fingers, thumb, wrist, or forearm?
Does the numbness or tingling affect your face? Around your eyes? Your cheeks? Around your mouth? Is one or both sides of your face involved?
Does the part of your body with numbness or tingling change colors? Does it feel cold or warm?
Do you have other abnormal sensations?
Do you ignore everything on the affected side?
How long have you had the numbness or tingling?
When did it start?
Does anything make it worse like exercise or standing for long periods of time?
Do you have any other symptoms?
Your doctor may also ask you questions to determine your risk for stroke, thyroid disease, or diabetes, as well as questions about your work habits and medications.
