Thanks for the replies.
Based on the initial X-Ray, my specialist recommended a course of 3 Shockwave sessions. My pain and mobility has significantly improved and I confirmed this in my last appointment. No further examinations have taken place since my original consultation.
I am most definitely improving so I'm now just a little unsure how to approach this. Although I've paid my £400 and my Shockwave treatment has ended he has kindly given me an open appointment to see him again within 6 months.
