there is a condition termed oropharyngeal cellulitis that is essentially a deep tissue bacterial infection of the neck and throat area. Its main symptom is swelling of the head, throat, and/or neck region. Amikacin has typical been the most effective antibiotic, however some of the more advanced cephalosporin class antibiotics may possibly work as well. I'm not saying that this is conclusively the cause of the swelling, but if it does not improve rather quickly, or suddenly advances, it is a strong possibility and rapid response will be required.
