Ouch eye mama, sounds painful. On the diet and exercise, we have been singing the praises of Balega socks. I got a pair that are ankle socks that are super soft and comfy. I have small feet and find that buying socks that come in sizes are good to keep blisters away for me.
I also like smartwool socks but don’t know if would work for you. Running socks in general are anti blister. Good luck.
