Hey Grandma_J!
I’m so sorry your feet hurt so damned much. When I say “I know the feeling”, I really do. (Unlike those unhelpful souls – pun intended-- who say that when you know darned well that they haven’t got a clue what it’s like to walk in your shoes.)
Right on this thread, @schoonerbird mentioned the good his Ritchie braces did for him. I told my pedorthist, and she thought that was an interesting idea, seeing they were usually used for foot drop. We put that idea on “hold” for another time. Then she disappeared on mat. leave.
Back to your question, though: nope, I’ve never known of anyone who’s had injections in their feet. If I were you, I’d start a new thread for that one, with the key words in the subject line. It’s got nothing to do with feet, but for what it’s worth (not much, probably) I had an injection in my spine
a few months ago which was a freakin’ miracle. But that was on one tiny spot for a pinched nerve, so nothing like your feet. The spine thing is a whole different story, unrelated (or so they say) to my PsA.
Those Crocs sandals have very firm soles. In my case, the less movement I have in my foot joints, the less it hurts. That’s why my “immobilizer” equestrian boots work so well. And the toe post on the sandals keeps my foot in position on the sole, which happens to be the right shape for me. Again, minimizing movement of the joints. I’ve thought that a pair of those air-cast things could work for me:
Oh, not such a good fashion look, you say?
It does sound like you’re doing everything that you can to minimize your discomfort. Have you tried tensor bandages or those food support things?
Have you had x-rays on your feet recently? If not, maybe you should: if there’s no damage visible yet, then perhaps the pain is being caused by inflammation and your PsA treatment needs to be reviewed. (Sorry if I’ve forgotten where you “are” with this.)
Don’t give up on this issue, Grandma, or @susieb17. If your feet are sore, and it isn’t damage (yet) keep after them. I wish I had.
