PE, I think my problem was made much worse when I sepia toned about thirty 16x20 prints when I worked for the AF back in the early 90's. I couldn't wear gloves because the prints were so slippery. It was the old rotten egg stuff. It took a very long time and I did it on my own time in my own back yard. My hands swelled to what seemed like twice their size and they were numb for days. After that they cracked and bled for awhile. My cuticles have never been the same.
Sodium sulfide solutions are very caustic almost as alkaline as sodium hydroxide. You may have suffered chemical burns which would account for the cracking and bleeding.
A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.
