Small red dots on the arm in the early stages of AIDS do not necessarily mean small red dots; small red dots may be caused by other conditions. The initial stage of AIDS may refer to the acute stage, which is about 2 to 4 weeks after infection with AIDS; patients will generally experience flu-like symptoms, such as fever, dizziness, headache, swollen lymph nodes, sore throat, muscle and joint pain, etc. A very small number of patients may be accompanied by night sweats, diarrhea, and rashes. For patients with a rash, it usually occurs on the arm, manifesting as a large red rash, which may also be accompanied by itching symptoms, and is generally not a symptom of small red dots on the arm; small red dots on the arm may be associated with purpura, skin allergies, perifollicular keratosis, and other conditions. To summarize, you can’t determine whether it’s AIDS simply by a certain symptom, and patients should seek medical treatment in time for a scientific diagnosis.
