I am in the military and do a lot of physical activities to include ruck marches. A ruck march is running in boats with 35 pounds on my back for a distance. The last one I did was 19 miles and after my arch is swollen and hurts on one foot and the other foot the third two is so painful I am having a hard time walking. Also after running my toes are going numb. Is there anything I can do for the pain and numbness.
