Hope you've been able to find some relief.I had heel spurs about 5 years ago and I remember them being very painful,my gp gave me an injection in each foot in 2 days time the pain was gone as yet to return.GP told me I had abused my feet wearing strappy high heels when younger in my disco days.You used to be able to buy from the chemist water filled heel pads which you put into shoes,they were good.
