Sorry to hear about that, my minor issues are nothing compared to what you describe and were never painful enough to need ibuprofen.
Well, thanks, but much to my surprise, over about sixteenth months of PostTib tendonitis, then breaking my ankle (or whatever, hairline fracture or a strain or sprain — never had an X-ray done, just didn't see the need), then Plantar Fasciitis, it's fine now. Stronger, faster, better. : )
Even 3x quod diem 800 mg boluses of iubuprofen doesn't exceed the maximum amount recommended in the OTC stuff.
More just an inconvenience, for me, it was.
But I will say, I've invested in a few pairs of steel-toed low-cut shoes. Swap out the insoles with one my favorite insoles, and they're actually pretty good for just walking around town (I work in a warehouse/distirbution/logistics for a day job, which involves a lot of walking on concrete and occasionally unloading or loading trailers). Not light-weight shoes, but the sturdiness is a bit of a boon: there's no worries if a pallet jack full of freight runs over your foot (although that's not supposed to happen!). I think mine are both Timberland Pro of the same model, but I don't recall the exact model. Not very comfortable, not like my Merrill trail-runners or similar.
However, the challenge is putting a shoe on over all the tape or an ankle-foot "boot" and assorted bits of velcro devices.
But, you get to pretend you're a gangster or an American Football player who just got shot or a concussion or whatever while you're limping around.
And, yet, at home I still stub my toes (all the time) and sometimes get pretty close to losing one or several of my toenails, thanks to my habit of being barefoot at home.
No, no, it seems to me that you have the worst of it. My recent maladies were comparatively minor.
Hey, at least I didn't break a hip, old-timer

No, but the plantar fasciitis didn't respond to any of the NSAIDs (ibuprofen, occasionally large-ish doses of aspirin), just debilitating pain, particularly upon first getting out bed in the morning.
But it does sound like you're still living with some of these problems, so all I can do is offer sympathy and do what your doctor or physical therapists recommend.
The other thing that's probably obvious, but I'll steal a phrase from one of Ray Jardine's books (arguably the founder of "ultra-lightweight backpacking," and a big denigrator of bulky "boot-like" sneaker/tennis shoes especially when hiking: hydration. I think he said something like "Don't be a sipper, be a gulper!" when it comes to water on the trail.
That sounds like elementary advice, and likely you already hydrate frequently and often, but many people I know IRL just plain don't drink water at all. I find it makes a difference. No, I don't necessarily mean sports drinks or whatever. Just loads and load of water. I suppose if you're concerned about overhydrating, you can take a salt pill like they used to include in military/backpacking pre-fab first-aid kits.
At least you didn't break your hands: then we wouldn't have more of your improvisations to look forward to.
