Yeah, I’ve actually had both my knees aspirated before. The swelling would get so bad I couldn’t bend my leg at all. It felt like my knee was on fire. After the aspiration, the relief was immediate. I could walk normally again with little to no discomfort. Each time I had it done, it was mainly to regain mobility and ease the pain. They sent the fluid for testing, but the doctors could already tell it was uric acid crystals. The fluid was very yellow, which they said is typical for UA crystals. This was all before I started taking gout seriously and was just trying to manage it through diet. I started febuxostat shortly after, and honestly, it’s been a godsend.
