I'm a senior developer who's forgotten how to code

I've been a developer for over 15 years. During that time, I've worked at huge corporations, startups, and even a 6-month solo stint as an independent contractor. With the exception of the past 2 years, I've always coded. I was senior, principal, even distinguished at some of these companies. I've written millions and millions of lines of code. <br><br>But I haven't written any code in the past 2 years. I've been a product manager, and it's caused me to forget how to code. Today, a developer showed me some code he had written and I looked at it like a second grader who can't read yet looks at a sentence full of words. I didn't get it. I didn't understand the syntax. I couldn't tell what the flow of the program was. I couldn't even understand it enough to know what to google. I've forgotten how to code. <br><br>What should I do? Convince my company to send me to a bootcamp? I feel like I need to take a month or two and just work through some Udemy classes or something. It's insane to me that I can't code anymore. Like, it's insane. I've been coding since I was 8.
