I am at risk of HIV infection. From week 5 to week 8, I experienced muscle and joint pain, fatigue, but no fever or swollen lymph nodes.

I have noticed that I often experience pain on my right hip, especially when putting weight on that side. For example, when bending down or leaning to the right, the pain is severe and I almost feel like I might fall if I stay in that position for a long time. What problem can cause such pain? Thank you very much.
