For the last few weeks I am facing with headache & stress. Specially in evening times. During headache & stress my both hands&legs feet area numbness?

Need further testing. You may need an ekg and possible stress test to rule out coronary artery disease. If negative a cervical and lumbar MRI recommended to rule out disc problems, spinal stenosis.
Test teeth. Check for teeth whether there are fillings and both hands and feet symptoms is a sign of systemic issue (environmental or toxins) would need cleanse a simple cleanse is with zeomins and mediclay you can get from http://healthline.Cc. If this does not get better do a testing with http://metametrix.Com - comprehensive urine organix profile to identify the cause of the problem.
