Hi.it is best if you consult with a doctor, preferably a general surgeon, for medical and physical examination. Based from your description, it could be a cyst (a sebaceous or a gelatinous type), a fibrous or a lipoma. These lesions can occur anywhere in the body and have the tendency to recur.  Management (medical and surgical) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
