RSIs never go away, you're stuck preventing flare ups and avoiding use when you can't.
I'd agree that it is likely that something in the OPs bike fit is off if he's doing something to his Achilles, but I'm also not a doctor, just someone with tendinitis.
I'm not unfamiliar with tendinitis. I also know that walking is just as repetitive as cycling and hurts much more when tendinitis does flare up. Tendons are also required for "working on the core" which I doubt his doctor would suggest either.
So are you suggesting that Podagrower simply stop doing anything until the tendinitis stops and go on bed rest? I doubt that's much of an option nor would it be good for him. I would still suggest a second opinion for someone who specializes in sport injuries than just a GP.
