Redness of the sclera?

Hello Doctor,
About a month ago, I had a cold.
Initially, I didn't see a doctor, but then the whites of my eyes started to turn red, so I went to see a doctor (both an ophthalmologist and a pediatrician).
The doctors suspected an adenovirus or herpes virus infection, so they prescribed me IDU and erythromycin eye drops and ointment.
I used them for about 2 to 3 weeks.
Although my cold has improved and the blood vessels on the surface of my eye have not spread further, they seem not to have constricted back, and the areas with more blood vessels are slightly swollen.
When I first started using the erythromycin, I experienced a lot of eye discharge, but now there is almost none.
I have finished the IDU, and since I will be abroad for nearly two months, the last doctor I saw in Taiwan said to let it heal on its own once I finish the medication.
However, I am now very concerned about my eyes because whenever I feel tired, both of my eyes turn completely red, and then they gradually return to a less swollen state once I am no longer fatigued.

Doctor, what should I do? Should I see a doctor again, or is there a way to reduce the redness and swelling? (Seeing a doctor in the U.S.
can be quite expensive.) I look forward to your response.
Thank you.

More Info

Red eyes following a cold can be a common issue, often resulting from viral infections that affect the eyes, such as adenovirus or other viral conjunctivitis. The symptoms you describe, including redness, bloodshot appearance, and swelling, can be attributed to inflammation of the conjunctiva (the membrane covering the white part of the eye) or other related structures.

Causes of Red Eyes After a Cold
1. Viral Conjunctivitis: This is often associated with upper respiratory infections. The adenovirus is a common culprit, leading to inflammation and redness in the eyes.

2. Allergic Reactions: If you have a history of allergies, the cold may have triggered an allergic response, leading to red, itchy, and watery eyes.

3. Dry Eyes: During a cold, you may breathe through your mouth more often, leading to dry eyes, which can cause irritation and redness.

4. Secondary Bacterial Infection: Sometimes, a viral infection can lead to a secondary bacterial infection, which may require different treatment.

Treatment Options
1. Artificial Tears: These can help alleviate dryness and irritation. They are safe to use frequently and can provide relief from symptoms.

2. Cold Compresses: Applying a clean, cold compress to your eyes can help reduce swelling and redness.

3. Antihistamines: If allergies are suspected, over-the-counter antihistamines may help alleviate symptoms.

4. Prescription Eye Drops: If your doctor prescribed IDU (Idoxuridine) and Erythromycin, it's essential to follow their instructions. If symptoms persist after finishing the medication, a follow-up with an eye care professional is advisable.

5. Avoiding Irritants: Stay away from smoke, dust, and other irritants that can exacerbate your symptoms.

When to See a Doctor
You should consider seeing a doctor if:
- Your symptoms do not improve after a week of treatment.

- You experience significant pain or discomfort in your eyes.

- Your vision becomes blurry or you see halos around lights.

- There is a discharge from your eyes that is yellow or green, which could indicate a bacterial infection.

- You notice any changes in your vision.

Conclusion
While it is understandable to be concerned about your eye health, especially when you are abroad and facing potential medical costs, it is crucial to prioritize your well-being. If your symptoms persist or worsen, seeking medical attention is advisable, even if it incurs some costs. Eye health is vital, and early intervention can prevent complications.
In summary, red eyes after a cold can be due to various causes, primarily viral conjunctivitis. Treatment typically involves supportive care, such as artificial tears and cold compresses. However, if symptoms persist or worsen, consulting an eye care professional is essential to rule out any serious conditions and receive appropriate treatment.
