The acute phase of AIDS does not usually cause a burning sensation in the back. AIDS is an acquired immunodeficiency disease caused by human immunodeficiency virus infection, which is mainly divided into acute phase, latent phase and AIDS phase. The acute phase usually occurs 2 to 4 weeks after infection, and some people may experience some non-specific symptoms similar to upper respiratory tract infection symptoms. The most common non-specific symptom in the acute phase is fever, which may be accompanied by malaise, sore throat and general malaise (similar to the symptoms of upper respiratory tract infection). 20% to 25% of the patients may have skin rashes, such as maculopapular rash, roseola, or urticaria. A few patients may have enlarged lymph nodes and neurological symptoms, which last for 1-3 weeks and then may resolve on their own. It is generally not specific and cannot be used as a diagnostic basis for AIDS. Acute phase usually does not cause burning sensation in the back. If you are worried about HIV infection, it is recommended that you go to the hospital to get a clear diagnosis so as not to delay your condition.
