The bubbles that you are feeling may be collection of fat (called lipomas
), or nerve
thickening (neurofibromas). Both of them do not need any specific treatment. A regular monitoring by doctor is advised. Also to confirm diagnosis it needs to be seen by a doctor. Usually both of these are not confined to the area that you have described and they are likely to be more widespread over the body. A careful examination may reveal some more of these in other places.
