I can understand your concern. You have cystic lesion on your shin.  It may be ganglion cyst or other cystic lesion. You should go for ultrasound study and if needed to go for fine needle aspiration cytology. It will give you exact diagnosis. Then you should take treatment accordingly. Complete excision is the treatment of choice. Consult your doctor and 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. </s>
