Prednisone
"This drug might be great for others, but for the few it is destructive. As it was for me. I had an allergic reaction from a bug bite on my knee, caused pain and swelling. So the doctor prescribed prednisone. Over 4 days, I experienced excruciating joint pain that led me to the emergency room (side effect of prednisone). I stopped it immediately, but over a year later I was diagnosed with avascular necrosis of the hip (bone death). I'm getting both hips replaced now and I'm 28 years old male with no prior medical problems. Look up other people's bad experiences with it, this drug made my life very difficult"
