I've made a few post about this little one already. Separating the post so I can get individual answers. When I first got him he did have what seemed like a little bump on neck but he had so many scabs from lice I didn't think much into quite yet. Today though, very noticible. It is hard. Does not move. Didn't seem to bother him. Does seem to "disappear" when in sleeping fetal position. Does this seem like an abcess? I do not see a opening or a scab anywhere near it. I am totally comfortable with sticking it with a needle to see if I can pull out discharge. (Have done it before on little critters I have hand reared and I am an MA.) But I also don't want to puncture it if it doesn't seem like an abcess or without having antibiotics on hand
