im under the impression if you have unders then you have drains, well thats the case for me anyway, ti could just be that you bleed more with unders, maybe if you bleed alot with overs then you will end up with drains too..xxx
I had overs and had drains,they were not in very long,it just means that any excess fluid will drain away from you,not everyone has drains,I suppose it is the surgeons decision and he will give you drains if he thinks you require them,xxx
