After 25 months of unprotected sex, why am I having various symptoms?

Hello doctor,

I have few questions to ask regarding my health problems. After 25 months of unprotected sex, I went for an HIV (Human Immunodeficiency Virus) test called comb AIDS (Accquired Immunodeficiency Syndrome) test, and the result came negative for both HIV-1 and HIV-2. At the same time, I also took a test on HBsAg, HVC(Hepatitis C virus), scrub typhus, Widal test, and blood sugar, but all the results were negative. I again retested comb AIDS test after three months, but the result came negative again. Not satisfied, I went for HIV ELISA (Enzyme Linked Immunosorbent Assay) test, but even this time, the result came negative. But presently, I am suffering from many problems such as, extreme tiredness, ulcers in mouth and tongue, weakness, reddish spots at the back, frequent thirst, frequent urination, pungent smell of urine, occasional itchy and spot eruption in private parts, occasional and pain in ears, itchy and reddish eyes, no energy to talk, easy catching cold, and uncontrollable sneezing. I recently got malaria, and I recovered after medication. Is there any possibility that my immune system was too weak to detect antibody after 25 months of unprotected sex? What is the period for HIV to become AIDS? Is it possible that I am already into the last stage for which the HIV tests gave a false negative result? Is there any further HIV test, which will give 100 % result about my HIV status? Some people suggest me to go for a CD4 (Cluster Of Differentiation) count and PCR RNA(Polymerase Chain Reaction Ribonucleic Acid). So, do I need to go for those test? What is the possible cause of all the symptoms that I mentioned? Lastly, I humbly request you to give a patient reading to my problems and answer my questions systematically. I will be grateful to you. Thank you.

Hello doctor,

Thank you for replying. I have attached the photos of the red spots on my back and ulcers in my tongue. I am still worried, and I once again request you to answer all the questions that I have asked previously so that, I will be relieved. Please take the trouble of answering me. Please look at the photos, and tell me what I should do further. And also, please tell me openly whether I am at risk or not. Thank you.

Thank you doctor,

I feel so lucky consulting an HIV specialist. Here are a few more problems, which I am undergoing. I have frequent urination and thirst, yellowish color and pungent smelling urine, pain in the legs while sleeping, extreme fatigue, less energy to talk, throat pain, itchy and reddish eyes, itching inside ears and occasional pain, ulcers in the mouth, and itchy private parts. Those are the problems I am presently suffering, which makes me feel that I am probably infected with HIV. I have never experienced so many problems in the past before the unprotected sex. But one good thing is that although I am so worried, my appetite is good so far. So, I would like to ask these few questions, begging you to answer me accordingly. What is the probable cause of the above problems other than the skin and ulcers problems? Some doctors say that in some people who are suspected to be HIV positive, but antibody test cannot detect them, then they are recommended for PCR RNA test. What would you say about this? Hoping that you will give a patient examination of all the problems that I have mentioned above, and also answer the queries that I have written below. Thank you.
