That is the medial ankle. Many have mentioned anterior and lateral strictures. And medial ankle sprains are rare.
The swelling seems to be primarily in the region of the posterior tibial tendon. An injury here can come on quite suddenly. A physical examination finding where the tenderness is would help confirm that even before imaging. So PT Tendinopathy/tendinosis or possibly even a partial tear are likely.
I will take your statement that the redness could be a red herring caused by the application of ice as true.

This is my swollen ankle - started this weekend and needed crutches to do my ward round. Glad to have made it to Milan, but I’m now paying the price! PS what’s my diagnosis? 😂

Two possible choices. Besides the genu valgum and pes planus. They are: Lived Reticularis or Box Jellyfish sting.
I'm leaning towards the Box Jellyfish.
And out of curiosity I ran it through ChatGPT. ChatGPT say I am incorrect and gives reasons for which it believes it is livedo reticularis.
How did spell check fair on these words. Awful!

Bill Maher's monologue recycles classic fearmongering by anthropomorphizing current LLMs as conscious beings that "want" to "live," blackmail humans, or "fight back." That's nonsense. Models like GPT and Claude generate outputs based on patterns in the training data, the immediate prompt, and the context. There is no inner life or "self" to protect.
The evidence is far weaker than the monologue suggests. Any appearance of "self-preservation" comes from prompted role-play or contrived, heavily engineered lab scenarios. Engineered stunts are being sold as evidence of sentient rebellion.
As Prof. Melanie Mitchell, a computer scientist at the Santa Fe Institute, put it: "The best thing we can do is real, fundamental science. We need to study AI systems with rigorous research methods, not improv games."
Real AI challenges do exist. But claiming today's models are plotting against us relies on exaggerations, misinterpretations, and emotional manipulation. We can summarize this clip as manufactured panic.
I'm hoping Bill will bring other experts to balance this, he usually does.

@drkeithsiau @redheadranting Don’t do this at home. No surgeon dips their instruments in a pot of boiling water to “sterilize” the instruments. They might put a tea bag in there instead.
I’ve found all sorts of things in feet; splinters, sewing needles and once a small Christmas tree light.

@redheadranting Have you thought about getting that removed? Might need some dissection but here’s a quick guide 💡

Sam Altman said people saying “please” and “thank you” to ChatGPT costs OpenAI tens of millions of dollars a year in compute. 67% of Americans do it anyway.
Run the math on why.
A 2024 Waseda University study tested LLM responses across politeness levels in English, Chinese, and Japanese. Impolite prompts produced measurably worse outputs: more bias, more errors, more refusals. Moderate politeness consistently beat both extremes.
The mechanism makes sense once you see it. Polite prompts pattern-match to higher-quality training data. When you write “Could you help me structure this analysis?”, the model pulls from professional, well-reasoned text. When you write “give me the answer,” it pulls from Reddit.
Google DeepMind’s Murray Shanahan explained it simply: the model is role-playing a smart intern. Treat the intern like a colleague, you get colleague-quality work. Bark orders, you get minimum-viable compliance.
Now look at the cost side. OpenAI handles over a billion queries daily. Each GPT-4 query uses roughly 2.9 watt-hours, ten times a Google search. But OpenAI just raised $40 billion at a $300 billion valuation. Tens of millions in politeness tokens is a rounding error on a rounding error.
67% of users do it anyway, and 55% of them say it’s because it’s “the right thing to do.” They’re maintaining a behavioral habit that governs every other interaction in their life. The parent who teaches their kid to say please to Alexa isn’t doing it for Alexa. They’re doing it because the alternative is raising someone who learns that being rude gets faster results.
Telling 900 million people to stop saying thank you so OpenAI can save 0.01% of operating costs is the most engineer-brained optimization take on the internet. You’re training yourself to treat every interaction as a transaction. And that habit doesn’t stay in the chat window.

@IhabFathiSulima In walking gait, after contact and during early mid stance it functions more as a brake on the forward motion of the tibia rather than acting to lift the heel off the ground.
