I have a lump about the size of a pea and and 2 smaller lumps one on each side. they are on the left side of the base of my penis where is meets the pelvic bone. They are hard and seem round and are not painful, but the pea sized one was previously smaller and i didn't notice the other two before. I understand that it could be a lymph node or cyst. But they seem connected some how almost like they have a ligament connecting them. Just wondering if you have ever heard of this?
