Hi
Welcome to the MedHelp forum!
It is difficult to comment without examining but the red dots could be petechiae. Petechiae are pinpoint-sized red dots under the surface of the skin.
The commonest cause of petechiae is a low platelet count (thrombocytopenia).
They can also result from autoimmune disorders, such as lupus or rheumatoid arthritis, bone marrow disorders such as leukemia, inflammation of the veins, as a side effect of certain medications including the vaccine itself, viral infections, such as EBV and septicemia or infection in blood. A complete blood count, urine examination and a blood culture may be required to reach a diagnosis. It is difficult to comment beyond this at this stage. Please consult your doctor. Hope this helps. Take care!
Are the little red dots on your arms? Wrists? hands? ankles? etc. I have them sometimes also but only on my arms, wrists and hands. there are usually only a few of them at a time and not to worry you but was one of my symptoms for my SLE. They only appear right before my Lupus flares. I don't know how much help that is but thought I'd share with you. Good Luck
