Hi,
Several possible causes of a lump in the lower back are accompanied by severe pain:
* Muscle Strain: A muscle strain or
sprain in the lower back can cause a lump or knot in the affected area. This can be caused by heavy lifting or sudden movements.
* Herniated Disc: A herniated disc occurs when the soft, jelly-like center of a spinal disc pushes through a crack in the tougher exterior casing. This can cause a bulge or lump in the lower back, which can put pressure on nearby nerves and cause pain.
*
Kidney Stones: Kidney stones can cause severe pain in the lower back, as well as a lump or bulge in the area. This is because the kidneys are located in the lower back, and kidney stones can cause swelling and inflammation.
* Spinal Tumor: A spinal tumor is a rare cause of lower
back pain, but it can cause a lump or bulge in the area. This can be accompanied by other symptoms, such as weakness or
numbness in the legs.
It is important to see a healthcare provider for an accurate diagnosis and appropriate treatment. Depending on the cause, treatment may involve rest,
physical therapy, medication, or surgery.
Take care. Hope I have answered your question. Let me know if I can assist you further.
