Recently i get toe pain and knee pain for a few minutes when im walking that hurts when i push to walk with the foot. it hurts when i put pressure with it. im not sure if its my bag or shoes or the way i walk quickly. could i have arthritis?

Take a deep breath. You are too young to concern yourself with arthritis. I would recommend seeing a podiatrist. I believe they can get directly to the problem of having pain while walking. They will exam your anatomy, how you function as you are walking or running . They can access your shoes and make Appropriate recommendations for your needs. It is possible you are still growing.
