For past few months iam having like vibrating and twitching sensation in my breast not continuosly but two or thrice a day i have the same feeling in someother parts of my body also .And on examining my breast there is no lump or depression no pain but when my breast arouses it's normal but when it rests its in a different shape other wise as it arouses it is normal. Is it something serious i becoming so restless because of this .
