Oh no, poor Winston! His face looks so sad. It sounds like he may be having an allergic reaction, and the lumps are hives. You need to take him into a vet immediately for treatment, as allergic reactions can progress to swelling of the face and muzzle, and subsequent respiratory distress. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.
