I had full protected sex with a commercial sex worker in Australia. Four weeks later, I experienced severe flu symptoms resembling HIV symptoms, and my girlfriend had similar symptoms and vaginal sores. We both tested negative for STDs and HIV at 4 weeks and 15 weeks post-exposure. I am still concerned about HIV and oral thrush, and I noticed small blisters on my penis after having sex with my girlfriend. I also feel enlarged lymph nodes in my neck and groin 9 months post-exposure. Am I completely negative for HIV with my 5.5-month test, and could I have transmitted HIV to my girlfriend? Is my oral condition oral thrush, and what are the blisters on my penis?

My 81-year-old father, who is otherwise healthy, recently traveled to India and experienced significant exertion, including going up and down stairs. Upon returning, he had swollen feet and ankles, with the left foot being more swollen than the right. The swelling reduced over time, but the left foot remains mildly swollen. He reports no pain, but I am concerned about the possibility of Deep Vein Thrombosis (DVT). What could be causing the swelling in his left foot, and should he be tested for DVT?
