<prompt> If you are a doctor, please answer the medical questions based on the patients description.had in 1985 hammer toes worked on with surgery to peg middle joint of toes together but in past year notices hard lump under 3rd toe next to baby toe that hurts when baby toe presses next to it the lump seems under the skin and seems to move slightly dont think its a calluos also im diabetic  <response>: Hi.based from your description, it could be a tendon cyst, lipoma fatty deposit or a fibrous fibrous tissue formation. Other lesions that must be ruled out are gout and arthritic lesions. It is best if you consult with a doctor for physical examination and clinical evaluation, especially if it causes discomfort for you. If its indeed a cystic formation, lipoma or fibrous, definitive management is excision and antibiotic treatment after. Hope this helps. Good day!! Chat Doctor.
