It is only visabel when she turnes her foot inwards thank you
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He may have some benign cyst like ganglion cyst, sebaceous cyst or other cystic lesion.  You should go for ultrasound study and if needed to go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
