My husband just had surgery May 14, 2012. He had two herniated disks removed, and now he has 6 screws in his back. Last night, he started complaining of tingling or numbness in his right foot and leg.. I need to now if this is normal, or is it something we should worry about.. Please answer my question.. We live in Mexico and cant afford to go back to the doctor to ask about this problem.. Thank you.
