Aching and swelling sensation in the knee a few days after a fall injury

Generally speaking, the knee refers to the knee joint. A sore or swollen sensation in the knee several days after a fall may be caused by factors such as bruising, muscle tension, muscle spasms, calcium deficiency, or arthritis. Patients should seek symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Bruising

After injury, blood vessels around the knee may be damaged, leading to local bruising. This bruising increases localized pressure and discomfort, thus causing a sore and swollen sensation.

2. Muscle Tension

To protect the injured knee, surrounding muscles may become tense and exert extra effort during walking or movement. This excessive tension and strain can lead to a sore and swollen feeling, especially in the muscles around the knee.

3. Muscle Spasms

Following a knee injury, surrounding muscles may contract and spasm to protect the damaged area. These spasms can cause a sore and swollen sensation around the knee.

4. Calcium Deficiency

Calcium deficiency resulting from picky eating habits may cause symptoms such as soreness, swelling, or weakness in the limbs. Under medical supervision, patients may take medications such as calcium citrate malate tablets or calcium carbonate D3 chewable tablets for treatment.

5. Arthritis

If a patient develops arthritis due to bacterial or viral infection following the injury, symptoms such as soreness, swelling, and limb weakness may occur. Patients should follow medical advice and use medications like ibuprofen capsules or celecoxib capsules for treatment.

If symptoms are severe, patients are advised to seek timely medical attention to avoid delayed diagnosis and treatment. Adequate rest is recommended in daily life to promote recovery.
