I’m so sorry this wound up sitting unanswered! I was just thinking of you on my day off as I was having some (unrelated) foot pain myself, and realizing I wasn’t sure how anyone might have resolved this for you. My last week was a ton of meetings, so I am afraid I forgot to check back in. My apologies this accidentally just got left.
I’m afraid the news you probably don’t want is what I have to give. If this happens despite trying a lot of different positions, I’d suggest you talk to someone in person about it. I actually think a good massage therapist is probably a better choice than a general doctor, though, which hopefully is within reach for you and less socially uncomfortable. Is this possible for you?
