Hi
Welcome to the MedHelp forum!
Numbness in calf and feet can be due to pinched nerve in the lower back (sciatica or lumbar spinal nerve getting pinched), Vit B12 deficiency, peripheral neuropathy of diabetes, hypothyroidism or Lymes, poor circulation, rheumatoid arthritis or Raynaud’s disease.
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Please consult your PCP as soon as possible to run tests and examination to clinch a diagnosis.
Take care!
Go to the Doctor or emergency room,as these could be signs of something major.The way you are feeling already is.pray,take it easy an dgo see the Doctor.God Bless you.
