Hi, and I can help a little. Severe left lateral recess refers to the foramen, or the spinal canal. That is the space in which nerves run. Any time your MRI STATES SEVERE, it is time to get a second opinion, and ask the doctors what their impressions are. When the words "Mild" are used, generally the condition doesn't warrent surgical intervention. If the disk Buldge or herniation pinch into the spinal canal, that HURTS! . May I ask you what your doctor has said so far? Stenosis also happens just with the aging process. It is when the nerve root, is being touched, or restricted that you begin to want to seek some help. Have you had any injections or PT so far? I will also look up any of the other information on there for you too. I google each seperate verterbre, and just write out what the words mean.
It is important to understand all of it. That way when you go back to the doctor, there won't be anything that you don't understand. Second opinion is really important. You want two doctors to concur with what the treatment options are. Surgery is always a last resort as you already know. I am sorry you are having these issues. I hope you can find a resolution that works and relieves your pain. ginnie
