<s>[INST] I have an odd rash I guess it would be called I am getting tiny redress dots on my lower arms towards the wrist on the right side there is a cluster 2 inches long by a half inch wide there is no pain involved and they are not lumping up on the skin. I have not been doing anything outside. I was just wondering if I should go to my Doctor and have it checked out or not it just started yesterday. [/INST] Hi, It sounds like a petechial rash which means tiny bleeding under the skin. There are many causes for the same: straining, medications, blood disorders, vitamin K deficiency to name a few. I suggest you get it reviewed by your concerned doctor for a thorough examination. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Smruti Pevekar, Dermatologist </s>
