My husband had a bulding disk at L2-3 for about 4 years and also some leg tremors. The tremors only happened when he laid down to sleep and were like severe shaking for about 30 seconds, subside, then begin again. The neuro thought is was epilepsy so has treated him with 4 mg. of Lorazepam and controlled it a little so he could sleep. In August the disk ruptured, went through months of PT with no help so had a laminectomy on March 11th. Now the tremors are out of control and his Lorazepam along with the muscle relaxers (methocarbomal 750) and percocet 7.5 are not controlling it which is not letting his back relax at night so is completely exhausted in the morning along with pain. Can you give me an idea of what it might be? My husband sees the surgeon on the 10th for postop.
Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with your doctor.
Without the ability to examine your husband and obtain a history, I can not tell you what the exact cause of his symptoms is. However I will try to provide you with some useful information.
Identifying the potential causes of your husband's symptoms of leg shaking is difficult without being able to view the shaking myself. Seziures are certainly one potential cause of leg shaking in general. Seizures are best diagnosed if the leg shaking is observed and fit with a seizure and/or if a brain wave study called an EEG is done during an actual episode of shaking. However, since the tremors only occur at night when he is lying down, seizures become less likely. Seizures are a potential diagnosis if the shaking is thought to be coming from the brain.
However, the spinal cord and even the peripheral nerves can be a cause of shaking as well, in which case this would not be called seizures. Other types of shaking occurring due to spinal cord or peripheral nerve problems include myoclonus and clonus. If your husband has disc disease of his spinal column which affects the spinal cord or nerves as they exit the spine, then this would potentially explain the tremors. Other points of historical important would include whether or not he has weakness or sensory loss in his leg.
I recommend that you follow-up soon with your neurologist, particularly if your husband is having weakness and/or numbness in his leg which would signify potential spinal cord or nerve involvement from his disc. If the episodes of shaking are consistent but would not be reproducible in your neurologist's clinic, it might be a good idea to video tape them so your neurologist knows what they appear like. Follow-up with your husband's surgeon is also important. Depending on the neurologist's and/or surgeon's findings on physical examination, additional testing including MRI of the brain or spine (Depending on what whether or not it is thought your husband's symptoms are seizures or from the spine) and/or a study of the nerves called an EMG/NCS may be ordered.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
