Small Red Dots on Skin: Possible Causes and Insights

Doctor, please help me?

Recently, I noticed small red dots on my arm and chest.
They are not very dense, but evenly distributed, and are hard to see unless you look closely.
They are about 0.01 cm in size (very, very small and red).
I visited a clinic and asked the doctor about it.
He mentioned that it could possibly be caused by a viral infection.
He also noticed a small spot on the right side of my tongue and suggested it might be related to a blood issue.
Could you please help me understand what this might be? The outpatient fees at the municipal hospital are quite expensive, so I would like to get an idea of what condition I might be dealing with based on my symptoms.

More Info

The appearance of small red dots on the skin can be concerning, especially when they are not accompanied by itching or pain. Based on your description, these small red dots, which you noted are approximately 0.01 cm in size and evenly distributed on your arms and chest, could be attributed to several potential causes.
One possibility is petechiae, which are tiny, pinpoint red or purple spots that can appear on the skin due to bleeding under the skin. This can occur for various reasons, including physical trauma, certain medical conditions, or even as a side effect of medications. If your doctor mentioned that there could be a viral cause, it might be worth considering viral infections that can lead to such symptoms, including viral exanthems, which are rashes associated with viral infections.

Another potential cause could be a benign condition known as cherry angiomas, which are small, harmless growths made up of small blood vessels. They are common and usually appear as small red or purple spots on the skin, often increasing in number with age. However, these typically do not appear suddenly and are more common in older adults.

If your doctor suggested that there might be a blood-related issue, it could indicate a need for further investigation. Conditions such as thrombocytopenia (low platelet count) can lead to the development of petechiae, and this would require a blood test to confirm.
Additionally, the presence of similar spots on your tongue could indicate a systemic issue, as the tongue can reflect various health conditions. For instance, certain vitamin deficiencies, such as vitamin B12 or folate deficiency, can lead to changes in the appearance of the tongue and may also be associated with skin changes.

Given that you have been advised to seek medical attention but are concerned about the cost of hospital visits, it is essential to weigh the potential risks of not getting a proper diagnosis. While over-the-counter treatments may provide temporary relief for some skin conditions, they may not address the underlying issue.
If you are unable to visit a specialist due to cost, consider looking for community health clinics or dermatology services that offer sliding scale fees based on income. Many cities have resources available for individuals who need medical care but are concerned about costs.
In summary, while small red dots on the skin can have various benign causes, they can also indicate underlying health issues that may require medical attention. It is crucial to monitor any changes in your symptoms, such as the appearance of new spots, changes in existing spots, or the development of other symptoms like fever or fatigue. If you notice any concerning changes, it would be wise to seek medical advice, even if it means exploring more affordable healthcare options.
