My 12 year old Mexican Hairless has swollen lymph nodes in her neck and shoulder/chest area. All four of her feet are swollen as well. About 2 months ago, I took her to the vet who diagnosed her with Lymphoma. She then sent me to an internist who exasperated the glands and sent it off to a pathologist. The results came back as not suspicious for Lymphoma. They also ran blood tests, checked her for mange, and finally decided it might be an allergic reaction. She took steroids and antibiotic(for an infection in her eye). The nodes decreased in size while she was taking the meds. Now, the swelling is back and possibly worse. I'm really worried about her and don't want to take her to the same vets. I'm going to try to get her into a different doctor, but I wanted to see if anyone had any ideas. The vet called her a "medical mystery". I can't imagine what it might be.
