Thanks for posting your query. I can understand your concern. I reviewed the picture.
It is petechiae. They usually occur whenever there might be some derangement in the coagulation profile or when you are intaking medications like aspirin and Clopidogrel to thin the blood.
It would be best to visit your doctor who can call for blood tests to check the coagulation profile and then decide the further course of action depending on the test results.
Please let me know if you have any queries. Take care
