How do i get rid of major heel pain from hiking to far yesterday?

Heel pain: Adequate heel support by using good fitting shoes. Trying insoles may also help.

Depends on the cause: Heel pain is most often caused by plantar fasciitis, a condition that is sometimes also called heel spur syndrome when a spur is present. Heel pain may also be due to other causes, such as infection, tendonitis, arthritis, stress fracture, nerve irritation, retained foreign body, bone tumor, or a cyst. Have it evaluated by a professional and get the appropriate treatment.
