To repeat what I said above: "Your symptoms are not typical for a new HIV infection. But to reassure yourself, get tested. You can expect a negative result."
Just do it. There is no point in staying worried or asking repeated questions on line. Suck it up and see a doctor or clinic.
am really worried about my symptom. still i have right knee pain.
No risk. Condoms work. No risk for HIV and no need for testing.
You had protected sex, so little or no risk for HIV. Your symptoms are not typical for a new HIV infection. But to reassure yourself, get tested. You can expect a negative result.
