I've had bad knee for about 3 months and it's got progressively worse to the point of me hobbling and limping around. I've had a cortisone injection from my GP last week and it's still painful, it doesn't feel much better. It seems most painful at the back and side of my knee.
What else can I do? I've tried paracetamol, hot and cold pads, knee supports, resting it, trying to walk through it.
