1.Electrical stimulation pain causes abnormal sensation after nerve compression, such as tingling like electrical stimulation. When the compression occurs in the cervical spine, the tingling radiates to the upper limbs; when the compression occurs in the lumbar spine, the tingling radiates to the lower limbs. 2, tingling and numbness patients often have abnormal sensations such as tingling, numbness, burning sensation, pins and needles. These symptoms can occur in the same area as the pain. 3.Muscle atrophy is caused by nerve irritation and interrupted or poor signaling from the brain. Nerve irritation can also be tested by examining the reflexes. 4, Problems with urination and defecationThese symptoms are very important because it can be a sign of cauda equina syndrome (caused by a herniated disc), which is an indication for emergency surgery. If you have problems with urination or defecation, or numbness in the perineal area, you should see your doctor immediately. All of these symptoms are caused by the herniated disc irritating the nerves. By interfering with the signals from the brain to the limbs and reflecting back to the brain, these symptoms are caused by the herniated disc pressing on the nerves. How is a herniated disc diagnosed? In most cases, your doctor can make a diagnosis of a herniated disc through a physical examination (checking sensation, muscle strength, and reflexes). An MRI can help in the diagnosis of a herniated disc. For patients, an MRI is only valuable if it is consistent with the findings on physical examination. Abnormal changes on MRI of the lumbar spine are sometimes normal in older patients. younger people in their 20s may begin to show signs of disc degeneration, which is typically seen in people in their 40s and 50s. This is why your doctor sometimes fails to notice it and it is noticed by the radiologist. Once a diagnosis of a herniated disc has been made, a treatment plan is proposed based on the patient’s symptoms, what is seen on physical examination, and X-ray and MRI results. Once the information has been gathered a rational treatment plan should be made.
