Unilateral calf cramps in the elderly may be caused by lumbar disc herniation, which can be accompanied by low back pain and sciatic nerve radiating pain in the lower limbs, and the symptoms are aggravated when the abdominal pressure increases, which needs to be actively corrected.
In addition, as we age, degenerative changes can occur in the spine of middle-aged and elderly people, and calf cramps can also occur due to pressure on the spinal nerve roots or decreased blood flow within the spinal nerve roots.
