hi i'm new to this forum, sorry for barging in. But felt i could put a few points. Numbness, sudden itch and kind of tingling sensation all related to nerves. I'm no doctor, but i have been diagnosed with sciatica caused by3 herniated degenerated disc of the spine.The back pain radiates down to my left leg and long hours of standing or carrying weight hurts. I was diagnosed in 2008. Sincere advice pls dont delay go meet an Ortho or Neuro. Hope you recover soon.View Thread
