What are the causes of soreness and swelling in the right posterior lumbar region for males?

Soreness and swelling in the right lower back of males are related to diseases such as lumbar muscle strain and lumbar disc herniation, and may also be caused by kidney stones. Here are the details:

1. Lumbar Muscle Strain

Lumbar muscle strain is mainly caused by prolonged sitting, standing, bending to carry heavy objects, excessive load, incorrect posture, colds, and other reasons. These factors can lead to degeneration of lumbar muscle fibers. Patients may experience soreness and swelling in the right lumbar region, accompanied by stabbing pain, burning pain, etc., which intensify during fatigue.

2. Lumbar Disc Herniation

Lumbar disc herniation is mainly caused by degenerative changes in the lumbar intervertebral disc, long-term repeated external force injuries, congenital abnormalities of the lumbar sacrum, and other reasons. Patients may experience soreness and pain in the right lower back, numbness and pain in one or both lower limbs, and other symptoms.

3. Kidney Stones

Kidney stones are caused by abnormally aggregated crystalline substances such as calcium, oxalic acid, uric acid, etc., in the kidneys. When the stones move, they can cause soreness and swelling in the back, especially smaller stones, which due to their high mobility in the kidney, can cause severe renal colic. Patients may also exhibit pallor, hematuria, nausea, and other symptoms.
