What could be the cause of pain in the left joint connected to the left hip?

Generally, there are many possible causes for pain in the left hip joint. Common ones include muscle strain, arthritis, and avascular necrosis of the joint. A detailed analysis is as follows:

1. Muscle Strain

Muscle strain is a common cause of joint pain, primarily resulting from overuse or physical exertion. It often occurs when leg muscles are injured due to intense exercise or improper work movements. This condition is usually accompanied by pain and swelling. If the pain is severe, patients may take oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen capsules or diclofenac sodium tablets, to help relieve pain and promote muscle recovery.

2. Arthritis

Arthritis is typically an inflammatory response caused by various factors, possibly triggered by viruses, bacteria, or other pathogens. Once pathogens enter the body, they can stimulate internal tissues, leading to excessive fluid exudation, increased pressure, and compression of nerve endings, resulting in pain. The most commonly used treatment for arthritis involves NSAIDs. Medications such as nimesulide tablets or ibuprofen capsules can be taken under medical guidance. However, if the condition is severe, surgical intervention may be required.

3. Avascular Necrosis of the Joint

Avascular necrosis is relatively rare but can still be one of the causes of joint pain. When blood supply to the joint is impaired, it can lead to hardening of the bone tissue, increased pressure within the bone marrow cavity, and consequently pain in the bone and surrounding areas. Ischemia in nearby nerves and blood vessels can also contribute to pain. In severe cases, pain relief medications such as ibuprofen capsules, diclofenac sodium sustained-release tablets, or celecoxib capsules may be taken under a doctor's supervision.

In addition, this type of pain may also be associated with conditions such as osteophytosis (bone spurs), lumbar disc herniation, or ankylosing spondylitis. Patients experiencing the above symptoms should seek timely medical evaluation at a正规 hospital and receive appropriate treatment based on their specific condition to prevent worsening of symptoms.
