i am still having many problems with severe back pain, numbness and pain in vaginal/rectum areas and inner left thigh and bladder and bowel probs, have to self cath ect and still no diagnosis as yet. Still sitting with a heat pad wedged into my you know what, really fed up. I got a copy of a letter that the neurologist sent to my gp with ref to my emg test but I haven't seen the neurologist {i need the results from the full spine mri I am having tomorrow first} so I don't know what this means as I haven't spoken to the doc.

{{''this lady's electrophysiology is quite clear in that it shows s1 innovated neurogenic change which is indicative of lumbar pathology'' }}

what does that mean in english please, and does it show there is nerve dammage? I cannot understand why my problems do not relate to the dermotone maps, s1 probs are not the same as the ones I have???? Anyone got any ideas please.

Thank you

An electro myo-graphy (EMG) is an electro-physiological examination that test the functionality of the nerves. Nerve functionality is, in fact, actual conduction of electrical impulses. This means that EMGs test nerve conductivity. For example, if a nerve is damaged ,its conductivity will have decreased and it will take a longer time for the electrical impulse to travel throughout the body. If a nerve is under pressure for a long period of time, neural degeneration can occur and its ability to function can become damaged. At the beginning, nerve damage manifests with signs of neural irritation: itching, burning and pain for the nerves of the sensory neural system and spasms manifest for motor nerves. Later, when the nerve degeneration is complete, symptoms of complete nerve failure occur: numbness for nerves of the sensory neural system and pareses and paralyses for motor nerves. During chronic degenerative diseases like spondylosis, various spondylotic changes (disk hernias and osteophytes) of the vertebral spine can create pressure on the roots of the spinal nerves and damage them. An EMG can only estimate the location of nerve damage; an MRI will visualize possible spondylotic changes that create pressure on the nerve.
