Hi @cjuln1, Welcome to Connect. It's frustrating to not know the cause for symptoms. I'm not a doctor, but do your symptoms sound like the symptoms of Morton's Neuroma?

"Morton's neuroma involves a thickening of the tissue around one of the nerves leading to your toes. This can cause a sharp, burning pain in the ball of your foot. You may have stinging, burning or numbness in the affected toes."

Have you discussed the symptoms with your doctor or a podiatrist?
