Hi I am new at this but i just had an MRI done and i have 3 herniated disks. one is ruptured and fragments broken off. The first one measured 10x10x18 and one measured 12 mm. Are these normal sizes or what? What is a normal size? I have excruciating pain in both legs with weakness, numbness and burning sensations. Does anyone have any responses? Thanks in advance for your input.
