Hi, I had gone through your question and understand your concerns. 
Itching, could be due to menstrual symptoms because in 
menopause ESTROGEN, which is an oil producing hormone on the skin starts decreasing and leads to dryness of skin.
Try  
-plenty of water to hydration
-use moisturizer
-cold water bath
-avoid sun 
it will start decreasing if it is due to menopause.
If not it may be due high 
bilirubin level(
jaundice), can be ruled out by LIVER FUNCTION TEST.
If you have rash like thing along with itching use LEVOCETRIZINE 5MG.
About your numbness in your left foot, use 
NEUROBION tablet. Check your BLOOD SUGAR levels to rule out 
DIABETIC NEUROPATHY.
Get a detail blood examination and consult a PHYSICIAN.
