A wound that's healing can produce a clear or pink fluid. An infected wound can produce a yellowish, bad-smelling fluid called pus.
Purulent Wound Drainage
Purulent drainage is a sign of infection. It's a white, yellow, or brown fluid and might be slightly thick in texture. It's made up of white blood cells trying to fight the infection, plus the residue from any bacteria pushed out of the wound.
“A wound that's oozing pus definitely means you have a bacterial infection,” said Dr. Brady Didion, a Marshfield Clinic Health System family medicine physician. An incision or wound that's healing well looks slightly red and may seep clear fluid. An infected wound may ooze whitish, yellowish or greenish pus.
Purulent drainage is not a characteristic of normal healthy wound healing. Exudate that becomes a thick, milky liquid or a thick liquid that turns yellow, tan, gray, green, or brown is almost always a sign that infection is present.
After the initial discharge of a bit of pus and blood, your wound should be clear. If the discharge continues through the wound healing process and begins to smell bad or have discoloration, it's probably a sign of infection.
Is It Good for Pus to Come Out? It can be part of drainage necessary for healing, but it can also be cause for concern. Don't encourage pus to come out, however. Doing so can cause or worsen infection, and it may make the skin more tender or even painful.
A small skin abscess may drain naturally, or simply shrink, dry up and disappear without any treatment. However, larger abscesses may need to be treated with antibiotics to clear the infection, and the pus may need to be drained.
When there is crusting around the scab, and it appears yellow, it is possible that the area has become infected and needs treatment with antibiotics. Anyone who thinks that they have an infected wound should speak to a doctor. Impetigo and cold sores are two common conditions that can also cause yellow scabs.
See your doctor immediately if you notice a change in color or odor of the fluid oozing from your wound. Purulent drainage is yellow, green, brown, or white and has a strong odor. The earlier an infection is caught, the easier it can be treated.
If the wound is closed, they can withdraw fluid or pus from the wound with a syringe and a small needle. This is called needle aspiration . The skin over an abscess might need to be cut to reach the pus inside. This is known as incision and drainage.
What to Expect: Pain and swelling normally peak on day 2. Any redness should go away by day 4. Complete healing should occur by day 10.
Pus is a whitish-yellow, yellow, or brown-yellow protein-rich fluid called liquor puris that accumulates at the site of an infection. It consists of a buildup of dead, white blood cells that form when the body's immune system responds to the infection.
If you have a scab, it's considered normal to see it change into a yellowish color over time. This is completely normal and is the result of the hemoglobin from red blood cells in the scab being broken down and washed away.
But pus is a natural part of the healing process for wounds. Pus is a sign that a wound is infected but it is also a sign that your body is trying to fight the infection and heal the injury. Once an infection has started, your immune system begins trying to fight it off.
After the bleeding stops or when the yellow water comes out, cleaning the wound is extremely necessary.
If your doctor placed gauze wick packing inside of the abscess cavity, your doctor will need to remove or repack this within a few days. You can expect a little pus drainage for a day or two after the procedure.
Is betadine good for pus? No, betadine is not advisable for pus. Betadine is ineffective if applied to an infected wound carrying pus or blood. You must clean the area before applying this medicine.
There are many different colors of pus, including whitish, yellow, green, or brown. The color is caused by the accumulation of dead neutrophils (i.e. white blood cells). In some cases, pus is accompanied by a foul smell. Pus appears green due to an antibacterial protein called myeloperoxidase.
The bottom line. Pus is a common and normal byproduct of your body's natural response to infections. Minor infections, especially on the surface of your skin, usually heal on their own without treatment. More serious infections usually need medical treatment, such as a drainage tube or antibiotics.
However, antibiotics alone may not be enough to clear a skin abscess, and the pus may need to be drained to clear the infection. If a skin abscess is not drained, it may continue to grow and fill with pus until it bursts, which can be painful and can cause the infection to spread or come back.
Once the wound has formed a scab, there is no longer the need to cover it with a bandage as the scab now acts as a protective barrier. Keep the area clean, but be gentle so that you do not accidentally remove the scab.
Is pus a good thing? “Nope,” says Dr. Derby. “P-U-S is B-A-D.” It's the byproduct of your body fighting an infection.
