What causes a bloating sensation in the knee area while running, and what should be done about it?

A feeling of swelling in the knee area during running may be related to factors such as lactic acid buildup, ligament injury, or synovitis. Treatment options include daily care, medication, and physical therapies. Specific analyses are as follows:

1. Lactic Acid Buildup

If running posture is incorrect or exercise intensity is too high, it may lead to lactic acid accumulation in the knee muscles, causing a sensation of soreness and swelling. This condition usually does not require special treatment and can be relieved with appropriate rest.

2. Ligament Injury

Incorrect running posture or overexertion may cause strain or tearing of the knee ligaments, resulting in pain and swelling in the knee area. Patients should rest adequately and, under medical guidance, may use heat therapy, massage, or other methods for recovery.

3. Synovitis

Frequent excessive exercise may trigger synovitis, leading to discomfort symptoms such as knee pain. Under medical supervision, patients may take medications such as ibuprofen sustained-release tablets or celecoxib capsules to alleviate symptoms.

In addition to the common causes mentioned above, knee swelling may also be related to conditions such as arthritis or meniscus injury. If symptoms persist without improvement, patients should seek timely medical evaluation at a hospital.
