Bump under chin
I was scratching under my horse today and I found a nickel size rounded bump. It is hard and doesn't cause any pain. It doesn't move much, but its kinda hard to tell on the other hand. I checked all the other horses in the barn for a similar bump but none had them that I could feel. It is located between the two curved jaw bones (not sure what the crevice is called) but it is just at the start of the curve if you are heading back the the throat latch. Kinda wondering if it would be a cyst, cancer, or even a body part lol .
