Persistent Red Dots on Skin: Seeking Solutions for Unresolved Issues

Red spots keep accumulating and do not disappear?

Hello, doctor.
I have been troubled by red spots for several years.
I previously visited a dermatologist who said I was bitten by fleas and advised me to apply medication.
I have been using the medication for a long time, but it has not been effective; the red spots remain and occasionally new ones appear in different locations.
I have consulted several dermatologists, and about 80% of them also said it was flea bites, so I continue to apply the medication, but there has been no improvement.
I looked up pictures of flea bites online, and I do not have any pus or raised bumps.
They are itchy, but the itchiness subsides after a day or two.
Some of the red spots do not even itch.
What should I do to eliminate these red spots? I have attached a photo: the pink circle in the middle shows the red spots that have been there for three to four years, and the orange circle indicates two new spots I discovered after showering today.
The main areas with red spots are on the palms of both hands (6 spots), one arm (3 spots), neck (2 spots), and thigh (1 spot).
When others see the red spots on my palms, they think I have some contagious disease, which adds to my stress.

Medical regulations state that "a physician must personally examine a patient before providing treatment or prescribing medication..." Therefore, online diagnosis is also not permissible.
If you are experiencing significant distress, it is advisable to seek medical attention promptly.

More Info

It sounds like you have been dealing with persistent red dots on your skin for quite some time, and I can understand how frustrating and concerning this situation must be for you. Based on your description, it seems that you have already consulted multiple dermatologists who have suggested that these red dots might be flea bites. However, since you have not seen any improvement with the treatments provided, it may be time to consider a few different approaches.

First and foremost, it is essential to ensure that you have a proper diagnosis. Flea bites typically present as small, itchy red bumps, often in clusters, and they can appear anywhere on the body. However, if the treatment for flea bites has not been effective, it is possible that the red dots could be caused by another condition. Some possibilities include:
1. Allergic Reactions: You might be experiencing an allergic reaction to something in your environment, such as certain fabrics, soaps, or even food. Allergic reactions can manifest as red, itchy spots on the skin.

2. Eczema or Dermatitis: Conditions like eczema can cause red, itchy patches on the skin that may come and go. These conditions can be triggered by various factors, including stress, weather changes, and irritants.

3. Folliculitis: This is an inflammation of the hair follicles that can result in red bumps that may resemble acne. It can be caused by bacteria, fungi, or irritation from shaving or tight clothing.

4. Petechiae: These are small red or purple spots that can appear on the skin due to bleeding under the skin. They do not blanch when pressed and can be a sign of various underlying health issues.

5. Other Skin Conditions: There are numerous other skin conditions that could cause similar symptoms, including psoriasis, hives, or even viral infections.

Given the complexity of skin conditions, I strongly recommend that you seek a second opinion from a dermatologist who specializes in skin disorders. It may also be beneficial to keep a detailed diary of your symptoms, noting when the red dots appear, any potential triggers, and the effectiveness of any treatments you have tried. This information can be invaluable for your healthcare provider in making an accurate diagnosis.

In the meantime, here are some general tips that may help alleviate your symptoms:
- Avoid Scratching: Scratching can worsen the irritation and lead to secondary infections. Try to keep your nails short and consider using cold compresses to soothe the itching.

- Moisturize: If your skin is dry, using a gentle, fragrance-free moisturizer can help reduce irritation.

- Over-the-Counter Treatments: You might consider trying over-the-counter hydrocortisone cream to help reduce inflammation and itching. Antihistamines can also help if the red dots are due to an allergic reaction.

- Avoid Irritants: Be mindful of the products you use on your skin, including soaps, lotions, and laundry detergents. Opt for hypoallergenic and fragrance-free options.

- Consult an Allergist: If you suspect that allergies may be contributing to your symptoms, consulting an allergist for testing could provide further insights.

Ultimately, the key to resolving your issue lies in obtaining a correct diagnosis and tailored treatment plan. Persistent skin issues can often be challenging to diagnose and treat, but with the right approach, you can find relief.
