Knee abscesses can be a concerning condition, especially when they develop in proximity to a joint like the knee. Based on your description, it sounds like you have developed an infection that has led to the formation of an abscess. Let’s break down the causes, symptoms, and treatment options for a knee abscess.


Causes
Knee abscesses can arise from various sources, including:
1. Infection: Bacterial infections are the most common cause. These can occur due to skin injuries, such as cuts or abrasions, that allow bacteria to enter.

2. Underlying Conditions: Conditions like diabetes or immunocompromised states can increase the risk of infections.

3. Previous Surgeries or Injections: If you have had any recent procedures near the knee, this could introduce bacteria.

4. Skin Conditions: Conditions like folliculitis or cellulitis can also lead to abscess formation.


Symptoms
The symptoms you are experiencing align with those of a knee abscess:
- Swelling and Redness: The area around the abscess is swollen and red, indicating inflammation.

- Pain: Pain during movement, especially when bending or standing, is common due to pressure on the surrounding tissues and nerves.

- Pus and Blood: The presence of pus and blood when you attempted to drain the abscess is typical.

- Systemic Symptoms: Feeling cold or experiencing chills, along with a general sense of malaise, can indicate that the infection is affecting your overall health. This could also be a sign of fever, which is often associated with infections.


Treatment Options
1. Keep the Area Clean: It’s crucial to maintain cleanliness to prevent further infection. Gently clean the area with soap and water.

2. Warm Compresses: Applying warm compresses can help promote drainage and reduce pain.

3. Antibiotics: Given the symptoms and the fact that you have systemic signs (like chills), it is advisable to see a healthcare provider. They may prescribe antibiotics to help combat the infection.

4. Drainage: If the abscess is significant, a healthcare professional may need to perform an incision and drainage procedure to remove the pus and relieve pressure.

5. Pain Management: Over-the-counter pain relievers, such as acetaminophen or ibuprofen (if not contraindicated), can help manage pain and reduce inflammation.

6. Monitoring: Keep an eye on the abscess. If it worsens, or if you develop a fever, increased redness, or spreading of the infection, seek medical attention immediately.


When to Seek Medical Attention
It is essential to consult a healthcare provider if:
- The abscess does not improve or worsens.

- You develop a fever or chills.

- You experience increased pain or swelling.

- There are signs of systemic infection, such as rapid heart rate or confusion.


Conclusion
In summary, what you are experiencing appears to be a knee abscess likely caused by an infection. It is crucial to keep the area clean and seek medical attention for appropriate treatment, including possible antibiotics and drainage. Given the potential complications associated with infections near joints, timely intervention is vital to prevent further issues.
