Thanks for posting your query.
You might suffering from plantar fasciitis
. It is caused by straining the ligament that supports your arch. Repeated strain can cause tiny tears in the ligament.
I suggest you to consult an orthopaedician nearby for a detailed examination.
Meanwhile give your feet a rest. Cut back on activities that make your foot hurt. Try not to walk or run on hard surfaces.
To reduce pain and swelling, try putting ice on your bottom of foot. Or take an over-the-counter pain reliever like ibuprofen
