Hi. I'm Dr. Lee and will do my best to help.
Can you tell me what exactly are the names of the injections?
Also, did your vet run any blood tests or any x-rays? If so, what were the results?
It appears that you are offline. If you can please provide the above information so I can better understand the situation and help. Once you reply, I will do my best to return to this chat as soon as I can. Thanks!
