Serious Problems That Sore Feet Can Indicate
Burning Pain

Extreme burning pain on the ball of the foot and base of toes could possibly be Morton’s neuroma. As fibrous tissue develops around nerves, they become compressed and therefore irritated. This is when the burning pain persists. Usually, the third and fourth toes are affected first and foremost. Steroid injections may be necessary or possibly surgery.
A burning sensation in the feet is also another common side effect of diabetes due to peripheral nerve damage. Experiencing burning in the feet can also be caused by a vitamin B deficiency, athlete's foot, hypothyroidism, peripheral arterial disease (poor circulation), and chronic kidney disease.
