Yes, you do need to have this evaluated by a surgeon
given the location of the lesion and the fact that you mention that the size seems to be variable. It is always a good rule to seek the guidance and experience of a professional with any lesion, but especially those that are in highly visible areas where cosmesis (how it looks later) is very important. Additionally, infections of the face that could develop by treating this yourself can be very serious as they could quickly spread to involve the brain. Finally, and perhaps most importantly, it is necessary to confirm that these are indeed benign cysts rather than a manifestation of another disease process that might be occurring. If it is a ganglion cyst, it can either be removed by aspirating (sucking the contents out with a needle) and then injecting the cyst with something that will (hopefully) keep it from coming back. Alternatively, a small incision could be used to remove the pouch that is housing the fluid. Generally, ganglion cysts come from small ruptures in the sheath that surrounds tendons or ligaments, and the area that you are speaking of would be slightly abnormal for the development of one of these. Please see a physician for correct diagnosis and appropriate treatment.
