Re: What does lumbar MRI mean?
Did you only have a MRI of the lumbar area? When I saw the word "hyper mobile" it raised a flag as one sign of cervical issues is a knee reflex that is hyper-reflexive.(more responsive than normal). When something like a bulging disc is pressing on the spinal cord in the cervical area, it can cause symptoms in both arms and legs as well as things in the head like headache, dizziness, etc. But the same thing happening in the lumbar area only causes symptoms basically from the waist down...there can be bladder and/or bowel involvement if the "cauda equina" is affected...but your report indicates this is only very slightly impacted.
Lumbar issues cannot cause symptoms in the arms or hands, shoulders, head.
Many of the symptoms you list could result from cervical nerve compression with the exception of the following:
Stomach - ibs symptoms
Allergies - nasal blockage
General ill feeling
As for the lumbar MRI, as your doctor said this report indicates that your lumbar spine is in good shape. The only exception to this is a small disc protrusion between the lumbar 4 and lumbar 5 vertebrae and some signs that this area is showing signs of mild degenerative change. The disc protrusion only becomes a problem when it is irritating or compressing a nerve and the report indicates "no significant caudal equine or nerve root impingement is seen." You can look online for a "dermatome map" which will show you what area is innervated by the L4 and L5 spinal nerves. It could explain some lower back pain and pain running down the back of the leg...but none of the other symptoms you mention.
Sorry that this MRI report didn't reveal an answer to all your symptoms...but I'm afraid you're going to have to keep looking. And I would look into a cervical MRI or at least ask the doctor about the possibilities.
