10 years exposure to HIV?

I am was exposed to HIV 10 years and after taking a test a month ago, came NEGATIVE.
But I am already esperiencing, fever for a long time, unknown headaches, weight loss, problems thinking and concentrating,
problems breathing, lung heaviness, fatigue, noices from my bones when I make a movement and Itching but no evidence of rashes.

Could it be that I have HIV and because it has gone untreated, it simply not showing up in the test?

Are there any other test I can take?

Please I need your help.

After 10 years a HIV negative test is over 99 % that is as close as you are going to get.

Most HIV tests are antibody tests that measure the antibodies your body makes against HIV. It can take some time for the immune system to produce enough antibodies for the antibody test to detect and this time period can vary from person to person. This time period is commonly referred to as the 鈥渨indow period鈥? Most people will develop detectable antibodies within 2 to 8 weeks (the average is 25 days). Even so, there is a chance that some individuals will take longer to develop detectable antibodies. Therefore, if the initial negative HIV test was conducted within the first 3 months after possible exposure, repeat testing should be considered >3 months after the exposure occurred to account for the possibility of a false-negative result. Ninety seven percent will develop antibodies in the first 3 months following the time of their infection. In very rare cases, it can take up to 6 months to develop antibodies to HIV.

Another type of test is an RNA test, which detects the HIV virus directly. The time between HIV infection and RNA detection is 9-11 days. These tests, which are more costly and used less often than antibody tests, are used in some parts of the United States.
