I hurt my hip /back a couple of weeks ago, and it went into spasm, I couldn't move, and the pain was unbearable. Painkillers had no effect, and during lockdown, this seemed to be the only option. Thankfully Cain agreed to see me - on VE day bank holiday, and was able to immediately put everything back into place. I'm more grateful than you can imagine that he helped when no one else would. Highly recommend.
