I had a surgery last January, broken labrum on both hips, left was "ok" and the right was really damaged, still it was an arthroscopic surgery and I could go on with my life 2 weeks after, but... 3 weeks after the surgery my right hip was getting worse, way worse, the pain was like nothing I have ever felt, I couldn't sleep, I couldn't walk, I couldn't even touch my fucking leg that I felt a nuclear bomb going off inside of it. No fever, puncture was ok, nothing that could deemed it as an infection. I was in literal agony, not even the strongest analgesics worked. I did a blood test and the PCR was off the charts, "yup, that's an infection, it's 10 AM, don't eat anything, today at 17hs you go in surgery".
I had a toilette done, infection was cleaned off but still I couldn't even move my leg, I lost all the muscle. Fast forward today, I had the worst 7 months of my life, antibiotics for 6 months but wait, there's more... Both infection and the initial cartilage problem evolved into a septic arthritis, last week I went into surgery again to have my hip replaced by a temporary spacer while the biopsy is performed and I will go in again in a month or so to get my definitive prosthesis.
For those who want to know, the bacteria was a Pseudomona.
So yeah, don't fuck with infections.
