<human>: I have a small lump/ round cyst-like ball under the skin on the arch of my foot. It is not a callus. Its failry dept into the foot. I am a runner and didn t know if part of my tendon on my foot has developed some odd swelling growth or what. It is not really painful but my whole arch has been hurting me on and off for a year. I just thought it was plantar faciitis.
<bot>: Hi, From your symptoms, it seems that you are suffering from plantar fasciitis. It happens due to inflammation of the plantar fascia. Painful lump on the foot could be countries are many things you can try to help your foot get better:Give your feet a rest. Cut back on activities that make your feet hurt. Try not to walk or run on hard surfaces. Use shoes with good arch support and a cushioned sole. Do toe stretches, calf stretches and towel stretches several times a day, especially when you first get up in the morning. For corn, you can apply corn cap. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care
