They spin your blood, extract the plasma proteins from your blood and inject it into the joint lining. They are healing factors.
It freaking hurt because my quad went into an immediate leg cramp. I did my best to calm myself. My husband was also there holding onto my feet in case I squirmed. But I didn't.
Yesterday was bad enough that I couldn't even go for a 10 minute walk.
Today I was able to do my mini-Pilates PT session and stretching, and I think I'll be able to walk, slowly.
the hip already feels about 40% better. Hopefully it's all better by early next week.
This could hold me for 1-2 years. Then we either get another shot, or I get the hip replacement.
