In my case I suffered from the below three symptoms:

• A dull ache was felt most of the time with episodes of a sharp pain in the center of the heel or on the inside margin of the heel.
• Often the pain was worse on first rising in the morning and after rest.
• It severely limited activities.
• Aggravated by prolonged weight bearing & thin soled shoes.

Pain is usually in the centre of the heel and can severely affect your lifestyle. I even had days off work because of this condition and had to stop attending the gym as running on the treadmill was very painful. In hind sight I should have treated the condition sooner to prevent the muscles from becoming severely inflamed.
