I had heel spurs in both feet - what pain! The only option my doctor gave me for a long-term solution was either surgery (ACK!), or...
stretches (I am not religious with them when I should be) -

and New Balance sneakers. I have gone back for follow-ups a few times, and kept asking when I could go back to wearing my cute shoes, or sandals in the summer.

The answer was, when I was ready for surgery.

So, I live in these sneakers. I have two pair so I can trade off every day, and make sure to not keep them more than 6 or 8 months (they look ok but the inner support is shot).
I get them on sale and with a coupon at Kohl's for about $35 - $40. They come in black if you need "dressier" shoes. They should be cross-trainers or running NB shoes with a good arch.

I miss my cute shoes, but I don't miss the pain. I can get away with something for about an hour or two, but I bring the sneakers with me to change. Even bare feet are terrible - at the start of treatment, the shoes had to go on as I got out of bed.

Try to use this time for some upper body - you can still play the swinging games (tennis, golf), do curls with canned goods, modified push-ups, etc.

Is there a pool that you can use?
