Is this kind petechiae a cause of alarm?

I notice my feet and legs have this red tiny spots. After researching from the internet, it fits all the symptoms of petechiae. Hence, i concluded it is. It only appears on my feet and legs. A few months ago, it was all around my body and i went to seek medical help. The doctor said it will disappear in a few days and indeed it disappeared. And he did a blood test for me. It was normal. Although the petechiae from my body, the one on the legs still remains.

The petechiae from my leg and ankles are very weird. They turned black or dark brown when i am resting on the sofa and it some or most disappear when i lie down for a long time. However, once i started to stand, it slowly turns red and more will appear when i walk for a very long time. However, when i sit and rest, it started turning brown. I think it is something due to circulation but i wan to seek some opinions.

Hello,
Purpura and petechiae are common after skin trauma and viral infections. They should go away in a few days. But if they persist then please consult a physician and get other causes ruled out which include allergic reaction, autoimmune diseases, thrombocytopenia, ITP or leukemias. Since you are getting it regularly without any trauma even , so your platelets need to be checked.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
