Aloha! You're speaking with Dr. Michael Salkin
I'm concerned about the inflamed joint because that isn't consistent with a flea saliva allergy for which she received an injection - most likely a glucocorticosteroid such as methyprednisolone. Is she favoring that leg? Licking at the joint? I need to consider an infected joint, a joint with structural damage, or even a malignancy at her age. Please take a look at this image - the hind leg is on your right - and tell me which joint is involved:
I'll await your reply.

Hi thankyou for your reply
It's her left hind knee joint she does lick this and pulls her leg away. It does not feel warm to touch spongy not hard.
Expert:  Dr. Michael Salkin replied 3 years ago.
You're quite welcome. "Spongy" suggests effusion - a joint distended with excess joint fluid seen most often with structural damage such as a torn anterior cruciate ligament. It's also consistent with malignancy. It's hurting her as evidenced by her licking and withdrawing the leg. You'll need to have the joint palpated by her vet and X-rayed to better understand what's going on in that area. I understand that we're not going to be performing surgery at her age and so a thorough exam is likely to be for academic reasons only. It would, however, give you a prognosis and possible conservative approach; for example, a nonsteroidal antiinflammatory drug (NSAID) such as meloxicam.
Please continue our conversation if you wish.

Thankyou so much for your advice I have arranged an appointment to see our vet tomorrow. Gut instinct tells me it's not good and just wanted to be sure. She is sleeping more than usual and tends to be wanting more human staying in the same position on the sofa for many hours

Hi my cats seen our local vet. She has received an antibiotic injection and also an anitinflammatory. I am taking her back in two weeks. In view of her age she's being managed conservatively. Thank you for your support
