I've had it for years.
I really, really, hope you can rid of yours quickly.
Cortisone seems to work for some, but not others. I can't remember now as it was a long time ago, but I decided it wasn't for me yet. Vague idea you can only do it so many times, or it can cause bigger problems.
Orthotic inserts seem to be a rip off. I was very very close to paying stupid money for some, but soon after the company went under & it was proven all the 'testimonials' were fake.
But on a slightly more positive note...
Buy yourself some crocs, I find the 'cheap ones' better than the 'genuine ones' as they're softer, but still very supportive & spongy. I ONLY wear them in the house well, mostly, occasionally I decide not to give a fuck & wear them out TRY not to walk around barefoot, especially on cold floors.
I've just bought some sketchers. I bought them in the US, I was bold over by the size of the range there. I got the GoWalk4 but there were others that had a higher heel than toe that I found weird but might suit you. I bought the ones with laces and they just look like trainers.
I wish I'd had more time to shop because their boots were AMAZING.
My feet still hurt, BUT, I wouldn't have been able to do half as much as I did in the US without them.
I buy Asics with GEL HEELS - for me the cumulus range is the best. It was better when Sports Direct sold them though!
Dense, but squishy flip flops are great in summer.
You can try the exercises -
1: Use a very cold can, put it on the floor and roll it the length of your foot, slowly, back & forth until it's no longer cold.
2: Put a tissue on the floor in front of your foot and use your toes to gather it towards you, straighten it out, do it again, rise and repeat.
3: Rotate your ankles & do exercises to stretch out your foot & calf muscles.
4: Rest.
5: Don't be afraid to take pain killers. My doctor had me on industrial strength & industrial doses & I had to take them on time, no waiting to get the pain.
I do know people who got rid of it quickly, so I wish you lots of luck.🌸
