Hello dear,
First of all, please do not self-diagnose yourself with the materials available online.
HIV cannot be diagnosed only with the basis of symptoms.
The complaints of burning sensation in hands & arms can be due to:
1. Any fluctuation in the blood pressure & blood sugar levels.
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.
4.
Hormonal & metabolic causes.
5.
Stress, inadequate sleep, etc.
So, kindly consult a Physician for proper clinical examination.
Investigations like
complete blood count, 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.
Take care.
