A couple of weeks ago, I had what looked like classic psoriasis under one nail. Kind of dirty looking under one edge (when it wasn't) that developed into a yellow streak inside the nail along the edge. Looked like I had a mustard stain in there. Also had the same color along a little patch of dug up skin along the outside of the nail, and a small piece of yellow "gunk" under the nail, which I removed. (Sorry for the graphic image there.)
The yellow stuff quickly disappeared. I still have the dirty looking area along the edge (too far in for dirt), now on two fingers. And that's it.
Now comes my question: Can psoriasis disappear that quickly or was it something else entirely?
