Just wanted to check in to see how you were doing? Were you able to get to a doctor? How has the stress been?
I didn't check out the photo as it's not a good idea to tell you what's happening from a photo- always best to get to a doctor in person and see what they have to say- but based on the information you gave, the bump could be something to do with your hand washing. It sounds like you might have some anxiety in the mix- I'd highly recommend seeing a doctor about that to see if that can give you some peace. If the bump doesn't go away after the excessive washing stops, definitely have a doctor check on that as well.
