I have had three so far, about a month between each one. The relief was great for ten days after the first, then less so for the other two. I'm not in agony, but I need time to sort out my knee when I first stand up, and I walk with a limp. Doctor seems to want to keep injecting steroid until I decide to go with the other kind. I'm planning to get a second opinion whenever I think I'm ready for another shot, but I gather the guy I'm seeing doesn't expect the steroid shots to last more than a couple of months. Wondering if this is typical.
