I seriously doubt any of the vets here could do the surgery. I was planning on a chiropractor for her anyway, but also noticed that she is not as rigid through her neck anymore. She is on joint supplement.
So from a year ago to now she became more flexible and the lump is soft now, way softer than other muscle tissue. Makes me wonder if she got kicked just before we bought her? She was a complete mess, we got her because we just couldn't leave her there and never expected her to be a performing member of the herd. I got before and after pics in my critters album, Snipper.
She's well bred and was a working ranch horse once. I'd be more than happy to just ride her around a little every now and then.
