Introduction
Knee pain, weakness while walking, and leg instability may be caused by factors such as calcium deficiency, hypokalemia, or degenerative joint disease, and treatment should be based on specific conditions. When the body lacks potassium, symptoms such as limb fatigue, muscle weakness, arrhythmia, and knee muscle soreness may occur. Under a doctor's guidance, medications like potassium chloride sustained-release tablets or potassium citrate granules can be taken to relieve symptoms.
Knee pain, weakness, and a feeling of instability while walking may be caused by conditions such as calcium deficiency, hypokalemia, or degenerative joint disease, among others. Treatment depends on the specific cause. Details are as follows:
1. Calcium Deficiency
Insufficient calcium intake can lead to symptoms of calcium deficiency, causing knee pain, leg weakness, insomnia, and numbness in the limbs. Under medical guidance, patients may take medications such as calcium carbonate D3 granules, calcium gluconate oral solution, or calcium carbonate D3 tablets for treatment.
2. Hypokalemia
When the body lacks potassium, it may experience symptoms including limb fatigue, muscle weakness, arrhythmia, and muscle soreness in the knees. Under medical supervision, patients can take medications such as potassium chloride sustained-release tablets or potassium citrate granules to relieve symptoms.
3. Degenerative Joint Disease
With aging, the knee joints may undergo degenerative changes, leading to symptoms such as knee pain, weakness, instability, and difficulty walking. Under a doctor's guidance, patients may take medications such as glucosamine sulfate capsules, glucosamine hydrochloride granules, or glucosamine hydrochloride tablets to support cartilage health.
In addition, these symptoms could also result from conditions such as knee synovitis, rheumatoid arthritis, or meniscus injury. It is recommended that patients seek medical evaluation at a hospital for accurate diagnosis and appropriate treatment.
