Painful Bumps from Sitting Too Long: Causes and Solutions

Prolonged sitting can lead to small lumps on the buttocks that are painful to the touch?

Hello Doctor, when I sit on my chair at home for a long time, I easily develop small lumps that feel painful to the touch on my buttocks.
Sometimes they go away on their own after a few days, and sometimes they become "ripe." I have squeezed them and they drain pus, which helps them resolve.
I remember that when I was studying, sitting for long periods didn't cause this issue, and even now at the office, my chair doesn't cause this problem.
However, I am concerned about these small lumps appearing when I sit on this chair at home.
Could it be that the chair is too hard, or am I sitting for too long? Thank you! :)

More Info

Painful bumps that develop from prolonged sitting can be attributed to several factors, including the type of chair you are using, your sitting posture, and the duration of time spent sitting. The bumps you describe may be related to pressure sores, also known as pressure ulcers, which occur when prolonged pressure on the skin restricts blood flow to the area. This is particularly common in areas where the bones are close to the skin, such as the buttocks.

Causes of Painful Bumps
1. Type of Chair: If your chair is too hard or lacks proper cushioning, it can create excessive pressure on specific areas of your body, leading to discomfort and the formation of painful bumps. Chairs that do not provide adequate support can also lead to poor posture, which can exacerbate the issue.

2. Prolonged Sitting: Sitting for extended periods without movement can lead to reduced blood circulation in the areas under pressure. This can cause the skin to break down, resulting in bumps or sores. It is essential to take breaks and change positions regularly to alleviate pressure.

3. Posture: Poor sitting posture can contribute to the development of painful bumps. If you are slouching or not sitting with your back straight, it can increase pressure on certain areas of your body, leading to discomfort.

4. Skin Conditions: In some cases, skin conditions such as folliculitis (inflammation of hair follicles) or other dermatological issues can cause bumps that may become painful, especially with pressure.

Solutions and Recommendations
1. Change Your Chair: Consider using a chair that is ergonomically designed for long periods of sitting. Look for one with good lumbar support, cushioning, and adjustable features. A chair with a softer seat may help distribute your weight more evenly and reduce pressure on specific areas.

2. Take Breaks: Implement a routine where you stand up, stretch, or walk around every 30 to 60 minutes. This will help improve circulation and reduce the risk of developing pressure sores or painful bumps.

3. Adjust Your Posture: Pay attention to your sitting posture. Keep your back straight, shoulders relaxed, and feet flat on the floor. Using a cushion or lumbar support can help maintain proper posture and reduce pressure on your buttocks.

4. Use Cushions: Consider using a gel or memory foam cushion designed for sitting. These cushions can help distribute your weight more evenly and reduce pressure on your buttocks.

5. Skin Care: Keep the skin in the affected area clean and moisturized. If you notice any bumps or sores, avoid squeezing or popping them, as this can lead to infection. Instead, keep the area clean and consider using a topical antibiotic ointment if necessary.

6. Consult a Healthcare Professional: If the bumps persist or worsen, it is advisable to consult a healthcare professional. They can assess the situation and provide appropriate treatment options, which may include physical therapy or dermatological care.

Conclusion
In summary, the painful bumps you are experiencing from sitting too long may be due to a combination of factors, including the type of chair, prolonged sitting, and posture. By making adjustments to your seating arrangement, taking regular breaks, and maintaining proper posture, you can alleviate discomfort and prevent the formation of painful bumps. If the issue persists, seeking medical advice is essential to rule out any underlying conditions and receive tailored treatment.
