Heel pain can be due to plantar fasciitis. It is swelling of a tissue in the heel due to various causes. You need to visit ortho/ sports medicine/ pmr doctors.
Next Steps
Further evaluation required to make a diagnosis but for now you can use silicone insole in sports shoes only ( no other kind of shoes should be wear) and start plantar fascia stretching along with contrast bath (heat and cold alternative 4:1 ratio)
