My one lamb's lymph nodes are swollen. The vet felt she needed to go on penecillin so I gave her her weekly round of shots. I don't think the lymph nodes swelling has decreased yet although I'd expect it to take some time for the swelling to decrease. Later I noticed that there are worms in their manure and now I'm pretty sure she's just chock full of worms. I've ordered a fecal kit so I can see what I'm dealing with here, but I was wondering if a mega infestation of worms would make her lymph nodes swell?
