I was standing in front of the stove and suddenly felt a hard spot under my toe.  I thought it was a piece of rubbish but it is a black lump that is a little painful when I put my weight on it. The lump is the size of a pea and makes it difficult to flatten my foot on the floor.
Hi! Good morning. I am Chat Doctor answering your query. From the history, it seems that you have got a corn in your foot which caused you such pain. If I were your doctor, after a physical examination of your foot, I would advise you for an excision biopsy of the lesion which possibly would come out to be a benign lesion giving it a cure. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor.
