[Concern] I have pain in the midfoot of my left foot. How should I manage it?

Recently, the front part of my left sole suddenly hurt so much that I couldn't walk, so I thought it would be okay after sleeping.

I endured it, but this morning I left early due to pain, though not as much as in the evening, and I went to the hospital.

They say it's metatarsal pain, but the term is very unfamiliar, and when asked how to manage it, they were told to wear cushioned sneakers.

They only told me not to walk too much... I found it a bit awkward... Right now, I have been avoiding walking quickly for over a week, but I have been walking about ten thousand steps slowly, and so far, the pain hasn't gone away.

But I'm worried I might get sick again... It was unexpectedly so painful that I found it hard to take a step forward. ㅜ,ㅜ

If anyone has similar symptoms, I would appreciate it if you could let me know how you are managing them^^
