I have a small lump under the skin on my temple.  You cant see it you can only rub your finger across my temple and feel a small bump.  I would say it is about half the size of a pea.  It doesnt cause any pain.  It makes me very nervous.  Could it be a tumor?  Ive noticed it there for a month.  I dont know how long it was there before then.
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.
