Is this condition cellulitis? How should I manage it?
Hello, doctor.
Twelve days ago (December 28, 2017), I fell while walking my dog and scraped my knee (the wound is approximately the size of a young woman's index and middle fingers).
I cleaned the wound with hydrogen peroxide and applied an antibiotic ointment (with ingredients similar to Neosporin) from home, then bandaged it.
I changed the dressing daily, but after two or three days, the wound seemed different: the open abrasion appeared to have shrunk, but there was redness and swelling around it, along with a slight itch.
I suspected I might be allergic to the antibiotic ingredients, so I stopped using it for two days, thinking it would improve.
I then only cleaned it with saline and used a hydrocolloid dressing, but after two days, I felt something was off.
The area around the hydrocolloid dressing developed small blisters that burst, and there were red spots (similar to what is described online as cellulitis).
The next day, I went to the emergency room, where the doctor prescribed antibiotics for two days (four times a day, two pills each time) and advised me to continue using my original antibiotic ointment.
I returned for a follow-up two days later (today), and the doctor examined me and instructed me to clean the wound and apply paraffin gauze, then bandage it.
He also prescribed another tube of antibiotic ointment (Neosporin), paraffin gauze, and pain medication.
However, the doctor quietly mentioned to someone nearby that it looked somewhat like eczema, so now I'm unsure whether to use the paraffin gauze or the ointment.
Is this condition cellulitis? If so, why am I not required to continue taking antibiotics? (During these two days on antibiotics, the wound has not shown significant changes and continues to exude yellowish fluid, with slight itching around the small spots; the redness and swelling have diminished slightly due to reduced movement.)

Hello! It is recommended to avoid using artificial skin for now and to use paraffin gauze instead.
Please do not come into contact with tap water.
Take care! Changhua Hospital cares about you!

More Info
Based on your description, it seems you are experiencing a complex wound healing process that may involve elements of cellulitis, allergic reactions, or even dermatitis. Let's break down your situation and clarify the symptoms, potential diagnoses, and treatment options.
Understanding Cellulitis
Cellulitis is a bacterial skin infection that typically manifests as redness, swelling, warmth, and pain in the affected area. It often occurs following a break in the skin, such as a cut or scrape, which aligns with your history of a knee abrasion from a fall. The infection can spread rapidly, and if left untreated, it can lead to more severe complications.
Symptoms You Described
1. Redness and Swelling: The redness and swelling around your wound are concerning. In cellulitis, the affected area is usually warm to the touch and may feel tender.
2. Itching and Rash: The presence of itching and small red spots could indicate an allergic reaction to the antibiotic ointment you initially used or a secondary dermatitis. This is not typical for cellulitis, which usually does not present with itching.
3. Fluid Drainage: The yellowish fluid you mentioned could be serous fluid, which is common in wounds, but it can also indicate infection if it is purulent (pus-like).
Treatment Considerations
1. Antibiotics: You were prescribed antibiotics, which is standard for treating cellulitis. However, if your symptoms have not improved significantly after a couple of days, it may be necessary to reassess the situation. Sometimes, the bacteria causing the infection may be resistant to the prescribed antibiotic, or the diagnosis may need to be reconsidered.
2. Topical Treatments: The use of antibiotic ointment is common, but if you suspect an allergy, it is wise to discontinue it. The use of a non-irritating dressing, such as paraffin gauze, can help keep the wound moist and promote healing without causing further irritation.
3. Follow-Up: Since your doctor mentioned the possibility of eczema or dermatitis, it’s essential to monitor your symptoms closely. If the redness, swelling, or pain worsens, or if you develop fever or chills, you should seek medical attention immediately.
When to Seek Further Medical Advice
- Worsening Symptoms: If you notice increased redness, swelling, or warmth, or if you develop systemic symptoms like fever, it could indicate that the infection is worsening.
- Persistent Symptoms: If the yellow drainage continues or if the itching and rash do not improve with the cessation of the antibiotic ointment, you may need to consult a dermatologist or an infectious disease specialist.
- Allergic Reaction: If you experience any signs of a severe allergic reaction (such as difficulty breathing, swelling of the face or throat, or hives), seek emergency medical help.
Conclusion
In summary, while your symptoms could suggest cellulitis, the presence of itching and a rash raises the possibility of an allergic reaction or dermatitis. It is crucial to follow your doctor's advice regarding wound care and to keep an eye on your symptoms. If there is no improvement or if symptoms worsen, further evaluation may be necessary to ensure appropriate treatment. Always prioritize communication with your healthcare provider regarding any concerns you have about your condition.
