Hello, It is due to prolonged weight-bearing which slightly compromise the blood supply and causes pain. As a first line management you can take analgesics like paracetamol or diclofenac for pain relief. If symptoms persist, it is better to consult a physician and get evaluated.  Hope I have answered your queries. Let me know if I can assist you further. Take care Chat Doctor.
