Lumbar 345 bulging disc can be left untreated if there are no obvious symptoms of nerve compression. If the compressed nerves cause numbness in the lower limbs, conservative treatments such as non-steroidal analgesic drugs (e.g., ibuprofen) and bed rest are feasible after MRI (magnetic resonance imaging) evaluation; if there is no relief of the compressed symptoms, surgery such as simple nucleus pulposus removal or laminectomy with decompression of the nerve root can be further selected. Lumbar disc bulge is the lightest category of disc-related diseases, the peripheral fibrous ring of the disc is not ruptured, and most of the patients are only MRI (magnetic resonance imaging) found that the disc bulge of the corresponding segment, there are no obvious symptoms, so they only need to follow the progress of the physical examination, and there is no need for treatment. When numbness in the lower extremities occurs signaling an aggravation of the herniation and the presence of some nerve entrapment, conservative treatment, i.e., bed rest and non-steroidal anti-inflammatory analgesic medications (e.g., ibuprofen), may be used for symptomatic relief. For patients with simple bulging discs, it is recommended to strengthen the low back muscles on weekdays, for example, swimming is a very effective exercise to enhance the muscle support around the spine, which can effectively reduce the probability of the disc developing from bulging to herniated and compressing the nerves in the future. If you have any symptoms, we recommend that you go to the hospital in time, and standardize your treatment under the guidance of your doctor.
