A herniated lumbar disc may cause hardness in the muscles.
The main symptom of lumbar disc herniation is lumbar pain. When the pain is severe, the muscles will be highly tense to protect the lumbar spine, as well as to relieve the pain caused by the lumbar disc herniation, and then the lumbar muscles will be touched with hard lumps.
It is also possible that when the pain is caused by a herniated disc, the muscle spasm is caused by keeping a position for a long time or repeating a certain action for a long time, and there is a feeling of stiffness in the muscle, which will cause a hard lump when touched.
Hard lumps in the muscles are not always caused by lumbar disc herniation, but may also have other causes, such as internal muscle scarring, adhesions, ectopic ossification, fibroids, etc. It is recommended to go to the hospital in time to find out the cause of the cause of the disease and then targeted treatment.
