Hi,  I am Yvonne aged 47 and the past 2-3 weeks I am experiencing tingling, numbness in my right foot predominatly but also my left and a little tingling in my fingers.  I have not been able to drive a car for the past 2 weeks because of no feeling in foot.  When I am walking it is fine, but just relaxing  and then the pins and needles/dead foot feeling arrises.  Is it serious ?thanks
Yes, you should go to your physician to examine you spine and the presence of sciatica. Lumber spine x-ray and CT scan will be done. This mostly symptoms of sciatica.
