Could it be this:
//Plantar fasciitis is inflammation of the plantar fascia, a part of your foot that connects your heel bone to your toes.
Symptoms of plantar fasciitis include pain around the heel and arch of your foot. It may be worse in the morning.
You can usually help plantar fasciitis with things like rest, ice packs and comfortable shoes. A foot specialist can help if it does not get better.
You're more likely to get plantar fasciitis from exercising on hard surfaces, wearing shoes with poor support or being very overweight.//
