I have pain on top of my foot, mainly when i walk. half way of the foot toward the left side of the left foot the pain started about 2 weeks ago, it happened after the pain in my heel disappeared

Without : Without more information, it's impossible for me to give you a meaningful answer. If you've been having heel pain and walking in such a way as to avoid pain in your heel, it's possible the pain you're getting now is just from overuse in walking to avoid pain. But it's purely a guess on my part. I recommend you see a podiatrist and have your foot properly evaluated to find out exactly what's wrong. Good luck and feel better.
