What Causes Terrible Pain In Ankle After Wearing Tight Shoes?

I sprained my ankle and then after I was fine, my soccer shoes were so tight and after a while of having them I started to feel horrible pain in my 4th metatarsal, so I went to the doctor after 4 weeks and I lived through horrible pain, they told me I had a stress fractured metatarsal the 4th one in my left leg. Now after 2 weeks of having the boot, I ve been experiencing tingling and burning under the metatarsal, why should I worry or just leave it and ignore it. The doctors said that I cannot do sports for 1 month but, I have to be 2 weeks with the boot and then I can t play for another 2 weeks, bur right now that I have the boot, I feel burning, numbness and tingling sensation should I worry.
