I would take her to the vet...If it is that big doesn't sound like something to mess with. I had a bunny that had one on his shoulder and I lanced it and cleaned it but it was small...Sounds like you are dealing with lots of infection.

I just did a Google on goat abcess and there is lots of info...including this one...Do a search and see if you can find info that will help..

Salivary Cysts are painless swellings on the side of the face that are filled with saliva. Do not lance a salivary cyst, because the salivary system provides vital bicarbonates needed in digestion, and to do so can result in life-threatening rumenal acidosis. Instead, use a sterile needle to aspirate (draw out) the odorless, colorless watery or slightly blood-tinged fluid from the cyst.

I looked into the search,
it isn't the salivary gland, and I don't think it is CL. When I tried giving her an injection in it of GSE I noticed she was bleeding pretty badly afterwards, I checked before I injected and it wasn't in a vein. Also when I gave her, her penicillin she bled after that injection. I injected it IM, not in the lump. I am at a loss and everyone I have called locally is at a loss, they think it is some sort of blood infection and it is manifesting in her lymph node. I am at a loss too. I would like to save the goat, but if it is going to be too dangerous to keep her, or to lance it off, then I don't know what else to do.

are you sure it's not a sliver? mine get that every now and then and it's usually a sliver that gets infected.

if it is a sliver,how do I get it out, I can't see anything, that looks like a sliver, perhaps it is all the way embedded.
However I have thought of that, you see, she will not eat out of her own feed bin, she puts her head between the slats of the pen and eats out of her neighbor's bin. and where the lump is, is right where her jaw rubs the wood.

i usually just squeeze it like a pimple and it pops out, generally has some pus with it, but if it stinks really bad could be CL. just to be safe, i usually catch whatever comes out and was myself and the goat really good with warm soap and water. i got rid of most all my wooden feeders, fences, etc and this has seemed to stop for me. have not had one in almost a year. the ones i did have it was very hard to see anything in the spot, but when squeezed it came out.

Thank you, I will try it this afternoon. I have been wearing gloves when ever I handle her,
The sad part is, if this is all it was, she was giving soooo much milk, and I didnt even have to fasten her in, I could milk her anywhere, she would let me. I stopped milking when this came up, and now she is almost dried up completely. Oh welll, I am still new at all this, only two years into goatship, and learn something new every day!!

I have a goat that had an abcess also on her jaw. However, she rubbed against something and burst it herself. I finished squeezing it out and put neosporin on it and it completely dried up. Might want to give that a try.
