I have a lump between pelvis & abdomen doctor said no hernia or tumors or cyst what could it be? It causes pain but not when I push down to it

Where exactly? Where exactly is the lump? Between pelvis and abdomen is too vague. Is it a superficial (ie. Can you see it?) lump or is it something that is internal that was seen on an ultrasound or a ct scan? Also important to know how big it is. What type of dr told you it was not a hernia, tumor, or cyst? Did they see it or are they also answering your question based on your description?
