Hello, I am new on this forum so I don't know if I'm doing stuff right but I am too distressed to read forum rules and tips and tricks so bear with me 
I have a cockatiel, (s)he is soon to be 9 year old, had him for about 8 yrs. I will be saying "he" because they said it was a male in the shop but I'm not too sure because of some of his typical female behaviour (he hadn't laid eggs though).
To get to the point, he has bumblefoot and he has been on antibiotics and it got better, but in literally a day, his left foot got swelled up again, and he won't stand on it, probably hurts him, and when I called the vet she said it wasn't an emergency but I'll get some more medicine to manage pain and to keep up with the antibiotic she gave me. Do you have experience with the sudden swelling even when it was getting better? It's too sad for me to watch him be fine one day and the next day he is limping... Do you know if it's easier on his feet to be on a soft surface, like laying on my chest or a pillow, or is it easier on his feet to stand on some perch? I will write the backstory in the next comment
