Our whole family and dog have this when I clicked on your images on Google they called them gaylebs. They say they cause fairly harmless tumors. We have been ill w them for at least 6 yrs. got them threw bad well water. I don't think they know a lot about them mainly because they called them fairly harmless. Since we've had them my daughter has developed leukemia, my husband hep c and I've tested positive for hep,Lupus and RA. The drs. say upon closer look I have none of these. They don't know what it is but they will eventually develop into a slug type thing. We all began losing our teeth. I had been an expanded functions dental assistant for 35yrs. Dentist don't look at extracted they just throw them out. I took mine home rinsed it and there was a thing attached. It had drained the blood supply from the tooth. I also had to have my ovaries removed and that dr said they were engulfed in cystlike things that had totally drained them. I have developed many more cysts and later this mo. I'm having one removed and examined. I've had a pathologist tell me it was made of a bacteria and yeast he had never seen. About the tiredness I'm only awake a very few hours a day. I only eat a sandwich a day and keep gaining weight. When I showed a parasitic specialist my tooth. He said how dare I bring in an animals tooth.wish me luck and I'll pray for you and definitely write back after the biopsy no one should have to live like this good luck
