My toe only throbs when I remove the tape, and it's hot - it throbs due to the swelling which can make the toe hard and the skin a bit shiny even.

Right now, I'm only using the Epsom lotion like you recommended, without any tape. It's swollen for sure, but more a purplish color. I'm going back to the podiatrist next week to ask about the bone. I'm not sure why he was so certain I should ignore the bone and it was fine after looking at the xray.

I never took any B12 supplement, just Calcium and Vit C. Since my neuropathy is trauma induced, it's less likely to be a deficiency I guess.
