Why do my Shines hurt so much! Everytime I work out

what are you doing? you can have shin splints or maybe you are just really exercisng the muscles behind and on the shin. maybe lay off doing calf and leg muscles or any running b/c running can also do minor damage to the shins. feel better

I'm working out on the treadmill
But after a while it starts to feel better

What about your sneakers? Are they old/worn out and are they appropriate for walking?

New sneakers have helped me in the past when my shins were hurting.

Your calves are stronger than your shin muscles, that's why. You can do this stretch; it'll help:

Sit on the floor with your legs straight and your feet in front of you. Have someone hold one of your feet, around the laces of your shoes. Try to pull your toes towards you as the person holding your foot resists so that you can't move your foot. You'll feel a nice stretch in your shins.
You can do exercises to strengthen your shins, like sitting in a chair, bare feet, take a towel, and put it by one of your feet and scrunch it up with your toes, then switch feet.

thanks everyone
