Hello dear,
First of all,
HIV cannot be diagnosed only with the basis of symptoms.
The symptoms like pus formation can be due to:
1. Immuno compromised status.
2. Persistence of underlying infection.
3. Inappropriate selection of antibiotics & incomplete duration of treatment.
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.
However, to relieve your concern regarding HIV, you can get HIV
ELISA test done.
As the exposure was 2 yrs back, the
antibodies if present will be easily detected.
Wishing you a good health.
Take care.
