Hello, I found firm, rubbery, quite movable, round lump, about 1cm in diameter (probably a little less) in my left arm crease. When i hold my hand straight, palm up, it's almost where I would have my blood taken, but about 2 cm to the right (closer to the body). First I thought it can be swollen cubital lymph node, but i thought they are a bit higher, above the elbow. Is the location consistent with cubital nodes, or does it point to something less scary (cyst, lipoma,...)? Thank you very much!
