Good Evening Sir.
First of all, I understand your worry.
But your symptoms alone are not suggestive of an
HIV infection.
The white spot in the picture just looks like some mucosal change, but it's not a proper well formed lesion, from what I can make out.
If it's bothering you a lot, I'll suggest you get yourself tested too.
But these symptoms alone, do not suggest an HIV infection.
Next Steps
Complete treatment, as given by your doctor.
Get an
HIV testing for reassurance.
Health Tips
Avoid smoking/ tobacco consumption.
