I had one shockwave session a week for three weeks - that's how Stanford does it. After those I felt no relief for about six to eight weeks, after which I could walk on flat surfaces relatively easily (after not being able to walk at all for 13 months from intense pain). I still could not climb stairs (which I have at home) or hills (where I live) without pain.
Therefore, a few months later I signed up for three more weekly shockwave sessions. Again, several weeks after the last one, I was able to climb stairs and walk in the hills.
I hope that clarifies things for you; let me know if not. Neither Shockwave nor PRP creates an instantaneous change. Gotta be patient and then some.
