my cat suddenly developed a swollen pink lower lip. took him to vet where he was examined - checked his mouth and felt round the throat and neck area. he gave me antibiotics after having a steroid injection. within a week my cat was back to normal i was so relieved. then 8 weeks later it came back, went back to the vets ! examined him again and said it was probably EGC complex. this time i got steroid tablets and have to have monthly prescriptions. the problem is he hates these pills and find it hard to give them. these pills should control swellings which can be caused by many things ie allergies often caused by fleas. must admit i do get worried about this condition i dont think there is actually a cure but my main concern was cancer. i wondered if a biopsy will be taken - but if so when ?
