Wound Healing Issues: Is It Cellulitis? - Surgery

Wound healing issues


I previously fell and had a large wound on my knee.
After a month, although the wound has healed, the surface is still red.
Initially, I thought it was just a scar, but recently I've noticed that if I gently press on the red area, it hurts, and it feels like the red area is expanding.
Could this be cellulitis?

Hello: A general wound (possibly an abrasion) that appears red on the surface after a month may be granulation tissue.
At this stage, the nerves are gradually growing towards the wound, which can cause tenderness.
However, if there is inflammation present, it can also lead to pain.
Cellulitis typically presents with symptoms of redness, swelling, heat, and pain.
It is best to consult a surgeon for a proper evaluation.
Thank you for your message!

When it comes to understanding wound healing issues, particularly in the context of your knee injury, it’s important to consider several factors that could indicate whether you are experiencing cellulitis or another type of complication.

Cellulitis is a common and potentially serious bacterial skin infection that can occur when bacteria enter through a break in the skin. It typically presents with symptoms such as redness, swelling, warmth, and pain in the affected area. In your case, the fact that the area around your knee remains red and painful to the touch, especially after a month of healing, raises some concerns. The expansion of the redness and the pain upon pressure could indeed suggest an inflammatory process, which might be indicative of cellulitis.

The timeline of your injury is also significant. If the wound was large and deep, it may have taken longer to heal, and any underlying infection could have been slow to manifest. The redness and pain you are experiencing could be a sign that the body is still fighting off an infection, or it could indicate that the wound did not heal properly, leading to complications such as abscess formation or persistent inflammation.

It’s also worth noting that while cellulitis is a possibility, other conditions could mimic its symptoms. For instance, if there is a collection of pus (an abscess) beneath the skin, it could cause similar symptoms. Additionally, conditions like contact dermatitis or other inflammatory skin conditions could also lead to localized redness and pain.

Given these considerations, it is crucial to seek medical attention. A healthcare professional can perform a physical examination and may recommend diagnostic tests, such as blood tests or imaging studies, to determine the underlying cause of your symptoms. If cellulitis is diagnosed, it is typically treated with antibiotics, and in some cases, drainage of any abscess may be necessary.

In summary, while your symptoms could suggest cellulitis, it is essential to have a healthcare provider evaluate your condition to rule out other potential issues and to initiate appropriate treatment. Delaying medical care could lead to complications, so it’s advisable to seek help as soon as possible.
