You're speaking with Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply. Please be patient. This may take a few minutes.

Expert:  Dr. Michael Salkin replied 16 days ago.

It could result in vomiting/regurgitation due to direct irritation at the primary site of a cancer; in other words, coughing/gagging resulting in a terminal gag and regurgitation of stomach and esophageal contents and vomiting/regurgitation could also arise secondary to metastasis of the cancer into his upper gastrointestinal tract. The swollen glands suggest that metastasis has already occurred. Diagnostics should also involve a needle aspiration of a swollen gland and microscopic examination of the aspirate looking for malignant cells. Please continue our conversation if you wish.

This all started after he had been in a field known to have ticks. Could this be tick bite fever? Just noticed what looks like a small tick on his eyelid
Expert:  Dr. Michael Salkin replied 16 days ago.

The hallmarks of tick-borne infections are fever, lameness, and bleeding tendencies. Swelling of the jaw as you described isn't consistent with a tick-borne infection.
