It also seems like eating carbs is terrible for inflammation. If I go slightly over normal carb intake my knee/foot will hurt. I have screws in there and I bet it's extra sensitive to inflammation.
Sounds like medically unsubstantiated anectdote.
It's not hard to believe that immune responses (allergic reactions being one end of that spectrum) are affected by the body's response to ingested substances. Especially given how strongly the gut microbiota affect blood chemistry.
It's also good to be aware of how strong the nocebo effect can be in this context. If you are convinced of the danger of something it can lead to significant issues. For an extreme example, severe airborne peanut allergy seems to be hard to be reproduce in controlled studies, yet there's people having significant symptoms from this, like lack of breathing etc.
Basically, when it comes to food, a lot of skepticism, including to our own experience, is often required. The risk is that we otherwise end up with unnecessary restrictive eating.
Personally I have a lot of things I "can't" eat, but even then, I try to challenge it now and then, sometimes I find something in a category I can actually eat and sometimes it turns out that I can eat it in low amounts or slowly learn to handle it.

High uric acid causes high blood pressure as well as gout.
High amounts of fructose, when digested, causes inflammation, and results in elevated uric acid.
Your body can digest small amounts of fructose in your intestines, which is why eating fruits (along with the higher fibre content) doesn't cause the ensuing inflammation.
Purines in beer can also result in high uric acid.
The inflammation from high intake of fructose causes your body to go into fat storage mode from fat-burning mode (bears/birds will increase fructose intake to increase fat storage before their long hibernation/migration south).
As humans get older, their body will adjust to convert glucose into fructose when sodium levels increase (by the time you notice your thirst from eating salty foods, your body has already switched into glucose->fructose conversion). read statements above to see what happens when your body processes fructose.
There’s a strong link with fructose and gout.
My diet is very clean. But at one point I lived in a country with an abundance of fruit and after about 2 years of indulgence I got a toe pain. Didn’t think much of it. Thought I just hit it. But then it lasted almost for a year. That’s when I got worried, did a bunch of reading. Fructose connection was a very clear one, where the traditional connection was actually not supported by evidence at all.
I reduced fruit intake significantly, and literally within days the pain went away.
And any time I eat lots of fruit a few days in a row the pain will slowly creep back in.
I think it just takes time. Perhaps liver clears out the purine and/or uric acid. From all the stuff I read before about fructose, even unrelated to gout, I think this mostly happens during the periods of fasting. So most likely at night and during deliberate fasts.
But to answer your question. I was eating about half a watermelon a day, plus some other smaller fruit. Then when I moved countries again, to yet another fruit abundant one, but with less watermelon access, I was eating 4-6 peaches per day.

"A quick search" determines that the main source of uric acid are dietary sources and that there are factors that might make its clearance slower. Fructose, if it's a significant factor, is down there in the list of things that should be checked
I'm not that invested in the topic, but I still think leaping to the conclusion that fructose suggests another commenter just has a crappy diet is borderline "personal attack" and also simply unfounded.
But, you know, whatevs.
Fructose simply isn't the only thing that contributes: Being male, eating some meat, fish, and seafood, being overweight, and so on can contribute. It isn't really processed meats that do it, but certain types of meat. Gout used to be a disease of the rich - who were the folks that were likely to eat the foods that lead to it (and have an amount of other contributors).
My brother got gout in high school: He wasn't eating too badly, was a healthy weight, but probably had a "rich" diet and was male.

I doubt I have gout, though, lol. I am a little over 6' and weight 73kg? I always associated gout with diabetes.
It’s more related to your ability to metabolize fructose which is a rabbit hole of a topic of itself. But a good science based overview is on YouTube. Check Sugar the Bitter Truth video.
The pain is more like the usual soreness from the injury, just worse.
