Glad you tested negative. Obviously an unprotected anal sex exposure is a risk for HIV transmission. But it is LOW risk at less than 1% for a one time incident. And your ab/ag test at 33 days is conclusive. You did NOT get HIV. Your ankle pain and heel pain is unrelated. Check the state of your shoes, they may need replacing which can cause those problems. Also physical activity with lack of stretching prior or cool down after can. But it's not hiv.
