First of all, HIV cannot be diagnosed only with the basis of symptoms.
The symptoms as mentioned in your post can be due to:
1. Any infection or sexually transmitted disease
2. Inadequate hydration status & electrolyte balance of the body.
3. Deficiencies of certain nutrients like Iron, Vit B6, Vitamin B 12, Folic acid
, etc. which helps in blood formation & nerve conduction.
& metabolic causes.
, inadequate sleep, etc.
So, kindly consult a Physician for proper clinical examination.
Investigations like complete blood count
, VDRL test, estimation of blood pressure & blood sugar levels will be helpful to rule out any pathological cause for the symptoms.
And regarding your concerns about acquiring HIV infection, I advise you to undergo certain tests like p24 assay or PCR for HIV.
These tests become positive within a week and are almost 100 % sensitive.
Even the presence of a single virus in the body can be detected by PCR.
So, if this test comes negative, you can be sure that you are safe.
Wishing you a good health.
