If a patient develops a pins and needles sensation all over the body, it is mainly caused by the stimulation of sensory nerves distributed throughout the body, not necessarily due to AIDS, but may be caused by various causes of peripheral nerve involvement. The main causes of peripheral nerve involvement include diabetic peripheral neuropathy, alcoholic peripheral neuropathy, and inflammation-related peripheral neuropathy, etc. Patients may experience pins and needles. Patients with AIDS may be asymptomatic in the early stages of infection, or may have non-specific symptoms such as low fever and malaise similar to a cold, chronic fever, infection that does not heal easily or chronic diarrhea, and a decrease in lymphocytes observed in blood tests. Chronic AIDS is an immunodeficiency and patients are prone to opportunistic infections in various systems, such as pulmonary Pneumocystis carinii, fungal infections, fungal infections of the brain, and toxoplasma infections.
