I definitely recommend that you go to see your primary care doctor
about this issue. There are several common causes of bad pain in the part of the heel that you are describing. Your doctor can take a look at the foot and help figure out what the likely cause is.
Although relatively rare, stress fractures of the bones in the feet do occur and they can be very painful. Most of the time these happen in people who have low bone density or in people who engage in very vigorous physical activity, such as long distance running. If your doctor things you have a injury

Another more common possibility is something called plantar fasciitis, which is an inflammation of the connective tissue that is right in front of the heel bone. This is essentially an 'over use' strain injury of the foot, caused most often by shoes that are not supportive, by standing on your feet for a long time, or by flat arches. If you are diagnosed with plantar fasciitis, your doctor can recommend anti inflammatory medications, as well as some stretching exercises to help relieve the pain.
