Agreed 100% My grandma takes in a bunch of abused horses and she had a few a couple years back and it was actually so sad. One out of 3 of the horses had to be euthanized. I could never imagine putting a horse, or anything in that matter, through something like that.
Not that I know of, I'm not usually one to hit my head on things. And I'm going to try get into the doctors when they open on Monday. Though the next appointments are likely over a month away hopefully I can get in quicker because it's rather concerning.
Yikes, have you been able to see like a doctor or someone in the medical field to get it checked out? Or did you accidentally bump into something causing the lump?
