  ...hmm. Not good. It's going to be alright. Where is the lump? If it's not in the same place as before, it's probably ok, and even if it is, that doesn't really say much. My grandpa had a clog in a vein in his neck once, and there was some lumpage after they operated...they said not to worry about it unless [insert unnatural non-homeostatic condition here, i.e. unusual fatigue, throbbing pain]. So dude...no worries yet, man.
