My soles hurt (worry)

I wonder if I have become a chronic patient... It feels like inflammation is spreading throughout my body. My shoulders have been sore for a while, and I occasionally experience lower back pain. These days, my soles often hurt. They don't hurt when I don't use them... What should I do? I walk a lot and need to exercise. For now, I am using less and bought insoles that support the arches from Coupang. I have been using them for four days. I try to challenge everything.
