Heel pain

Almost three weeks now that i enduring the pains of my left heel. I was thinking i got these pain due to my new flat sandal so i choose not to seek a medical attention. After 2 weeks the pain become severe during early morning if i get up from my bed or if i stand up after a prolong sitting. I can't bear the pain anymore and the pain is going higher of my legs. I was thinking i have already a severe bursitis, arthritis or any condition on bone or joint disease so i decided to decided to see a doctor without delay. From the Out Patient Officer of the clinic referred me to Orthopedic surgeon. I will post the result of my doctor's check up tomorrow.
