Flea bites can be quite bothersome and may lead to a range of symptoms, including redness, swelling, itching, and pain, as you've described. When dealing with flea bites, it's important to understand how to manage the symptoms and when to seek medical attention.

Flea bites typically appear as small, red, itchy bumps that can sometimes form a triangular pattern, especially if multiple bites occur in close proximity. The initial itching is caused by the flea's saliva, which can trigger an allergic reaction in some individuals. In your case, the progression from itching to redness and swelling indicates that your body is responding to the bites, which is common.

Here are some steps you can take to manage flea bites at home:
1. Avoid Scratching: While it can be tempting to scratch the bites, doing so can lead to further irritation and increase the risk of infection. Try to keep the area clean and avoid touching it as much as possible.

2. Topical Treatments: Over-the-counter hydrocortisone cream can help reduce inflammation and itching. Antihistamines, such as diphenhydramine (Benadryl), can also be effective in alleviating itching and discomfort.

3. Cold Compress: Applying a cold compress to the affected area can help reduce swelling and numb the area, providing temporary relief from itching and pain.

4. Keep the Area Clean: Wash the bites gently with soap and water to prevent infection. After washing, pat the area dry and apply any topical treatments.

5. Monitor for Infection: Keep an eye on the bites for signs of infection, which can include increased redness, warmth, swelling, pus, or fever. If you notice any of these symptoms, it’s important to seek medical attention.

Now, regarding when to see a doctor, consider the following:
- Persistent Symptoms: If the redness, swelling, and pain do not improve within a few days or worsen, it may be time to consult a healthcare professional.


- Signs of Infection: If you notice any signs of infection, such as increased warmth, pus, or fever, you should see a doctor promptly.

- Severe Allergic Reaction: If you experience symptoms beyond localized redness and itching, such as difficulty breathing, swelling of the face or throat, or widespread rash, seek emergency medical care immediately.

- Underlying Health Conditions: If you have a weakened immune system or other underlying health conditions, it’s advisable to consult a doctor sooner rather than later.

In summary, while flea bites can often be managed at home with proper care, it’s crucial to monitor your symptoms closely. If you experience persistent or worsening symptoms, or if you have any concerns about infection or allergic reactions, don’t hesitate to reach out to a healthcare provider for further evaluation and treatment. Taking these steps can help ensure that you recover quickly and avoid complications.
