No specific injury that I can recall... The seam in the nails has been an off and on issue for the past year or more. The seam on the left thumb finally grew out and went away but the one on the right thumb just never grows out. That's the one (obviously) that is having the issues now. Working with the goats and in their pen, I suppose I could have picked up some poop or whatnot but I DO try to wash my hands as soon as I am done and get back inside.
I'll pull the band aid in the morning and see if I can squeeze anything more out, give it another soak and just keep an eye on it for a few days. I'm on a 7 day course of antibiotics right now for a UTI that I didn't know I had but turned up in the lab results from my last Dr appt. a few days ago. I expect/hope that will help as well.
