I used to have the same problem and went to see a podiatrist. I had pain below my toes and the reason was that the mechanics in my foot was incorrect and my weight was not destributed correctly (and I'm not a heavy person). The joint @ my big toe was too mobile and was shifting the weight towards the other toes. It mostly happened when I was walking on hard floors barefoot or really hard shoes. I have moderate bunions which was part of the faulty mechanics. I also had back pain, which I think was as a result of my feet problems in addition to being tall. That's why I decided to have the surgery. You should probably see a podiatrist, the x-rays are going to show exactly what your problem is. It might be something easy to fix, good luck
