    Hi,

    What causes chronic nerve injury or chronic radiculopathy?

    My MRI shows granulation tissue without compression on S1 nerve root.

    My ENG and NCV shows normal.

    Is chronic radiculopathy same as nerve damage?

    According to my surgeon he says scar tissue on nerve root but no compression and weak ankle.

    Chronic nerve injury is caused by compression or inflammation of the nerve that damages the normal day to day function of the nerve. Please read the section on EMGs and you will find out that an EMG can be normal in the face of nerve injury. Read the section on chronic radiculopathy to understand this concept further.

    However, if there is muscle weakness present (motor damage), an EMG will be able to identify this disorder. Remember that these tests are run and interpreted by individuals who may miss findings due to technical or other problems.

    Thanks. Still having pulling sensation and tightness at the back of my leg. ANKLES ARE TIGHT TOO. In term of motor issue I am much better. Before the surgery I was totally bedrinner and just sit on the wheelchair. 4 MONTHS after the surgery I stop using crutches but I still limp when I walk. The muscle weakness are improving.My main problem now is the leg pulling sensation and tightness at the back of leg and both sides of my ankle. Before surgery the pain was unbearable that required me to have pethidine IV 100mg and dynastat. After the surgery the pain reduced.Immediately after surgery I was given 300mg 3 times a day of neurontin, targin 10mg, arcoxia 120mg and 2 tqb 3 times a day of ultracet. Currently I am still on those tablets. The pain now is still the same after the surgery but the muscle weakness improved tremendously. I have been to PT and I tried acupuncture and pens treatment but it did not work for me. I also had epidural steroids injections but it failed too. I was wondering is it possible that those granulation tissue causing me the pain even though there is no compression or the sensory nerve is damage. For the motor nerve is still in a healing process. I am still going for my pt. My back hurts too if I walk or sit or stand for too long. Is it possible to have sensory nerve damage with a normal motor nerve.

    Thanks. So sorry for asking u so many things. Your article is pretty confusing for me because I am not very good in science. I am just help my friend in the pharmacy . I better with medications knowledge.

    Pulling and “tight” sensations are typical for nerve injury symptoms. Think about the time you have had numbing injections in the jaw for dental surgery. When the jaw is numbed, it feels swollen and “heavy” and this sensation lasts until the numbing medication wears off.

    The same type of sensation experience occurs with nerve injury but since the nerve does not quickly recover, this sensation is unfortunately maintained.

    It looks like the surgery was a partial success as you can now walk where before, you were confined to a wheelchair. The question still remains if you have a degenerative spondylolisthesis at L4-5 or L5-S1 and compression above your prior microdiscectomy, can further surgery give you some relief?
