I can understand why you are so concerned. It sounds like you are dealing with it early. That’s a great thing!

I was diagnosed with plantar fasciitis years ago. Mine was more in my middle foot and not the heel, but later I had heel involvement, that wasn’t painful. Had a clicking sound in one heel. The best thing I did was start wearing orthotic shoes and there are some that are fashionable. Try Vionic. It’s an investment but quite helpful. Your doctor might recommend inserts. I never cared for inserts, but if you have pain, good support worked wonders for me.

I would encourage you to pursue the issue and get answers, if possible. Ask them to explain the reasoning for the diagnosis. And, please ask for a B12 blood test, before you start taking any B12. Getting the initial number is crucial. None of my doctors ordered that for me when I had foot issues, some tingling too. I’m now seeing a neurologist about it, but everyone might not need that.

I hope you can get your concerns addressed and issues resolved. Please post your results.
