I looked up that minocycline is an investigatory drug for HIV
because it can potentially reduce replication and activation in latent infected HIV
cells, primary CD4+ cells.
Around 4 months post exposure, I stopped taking this and almost immediately had a strange ache in my knees and elbows, knees especially. In addition, 5 weeks after this, my girlfriend of 3 years (not the potential exposure) got a flu like illness with swollen lymph nodes in the neck and a week of diarrhea.
