Post-Hospitalization Redness After Cellulitis Treatment

Cellulitis

Hello, my dad is about 56 years old and was hospitalized for a week due to cellulitis in his lower leg, which caused a fever.
He has been discharged for two days now, and while his leg no longer hurts, it is still red.
What could be the reason for this?

Dr. Lin Wufu reply Internal Medicine

Hello, the most common reason is swelling after an infection, which usually subsides gradually when lying down with the affected area elevated.
However, if you stand or walk for a long time, the redness and swelling may return.
This is related to poor blood circulation following the infection, and some individuals may take one to two months to improve.
It is recommended to continue follow-up visits with the original treating physician.

More Info

Post-hospitalization redness after cellulitis treatment can be a common concern, especially in patients who have recently undergone treatment for this condition. Cellulitis, an infection of the skin and underlying tissues, often leads to inflammation, swelling, and redness in the affected area. While your father may no longer experience pain, the persistence of redness can be attributed to several factors.

Firstly, it is important to understand that the skin and tissues can remain inflamed even after the infection has been treated. This inflammation is part of the body's healing process. When the body fights off an infection, it sends white blood cells and other immune components to the affected area, which can result in redness and swelling. This process can take time, and it is not uncommon for the redness to linger for days or even weeks after the acute phase of the infection has resolved.

Secondly, the redness could be due to residual edema (swelling) in the tissues. After an infection like cellulitis, the body may retain fluid in the affected area as part of the healing process. This can lead to a prolonged appearance of redness and swelling, even if the infection itself has been cleared. Elevating the leg and applying cold compresses can help reduce this swelling over time.

Another consideration is the possibility of a secondary infection or complications. While your father may not be experiencing pain, it is essential to monitor the area for any signs of worsening redness, increased warmth, or the development of new symptoms, such as fever or discharge. If any of these occur, it would be prudent to consult a healthcare provider to rule out any complications.

Additionally, the use of antibiotics during hospitalization can alter the normal flora of the skin, potentially leading to a temporary imbalance that may manifest as redness or irritation. This is particularly true if your father has a history of skin sensitivity or allergies.

In terms of management, it is crucial to follow up with the healthcare provider who treated your father. They can assess the redness and determine if any further intervention is necessary. They may recommend continued monitoring, additional imaging if there are concerns about underlying issues, or even a course of oral antibiotics if there is suspicion of a secondary infection.

In summary, the redness in your father's leg after treatment for cellulitis is likely a result of the body's natural healing response, residual swelling, or possibly a secondary issue. While it is generally not a cause for alarm, close monitoring and communication with healthcare providers are essential to ensure a smooth recovery. If the redness persists or worsens, seeking medical advice is the best course of action.
