Knee Swelling – Elderly Patient. Out!

Greetings Doctor, I hope you are doing well. I am reaching out regarding my grandmother. Over the past few days, she has been experiencing significant swelling in her right knee and is currently unable to walk even a step due to the pain. She has been on heart medication for the past few years, and her cardiologist had previously prescribed medication for her knee as well. However, this issue has been recurring frequently. Considering her age and the level of discomfort she is going through, I kindly request your guidance on what can be done next for her treatment and relief. I have attached her current knee photo along with her heart medication prescription for your reference. Thank you in advance for your support.
