I have had a cottontail for about 4 months now, and has been a rollercoaster ride to say the least.. she has gotten these weird owies on her whicj sometimes look like giant cuts and it's horrible.. have t had one of those for a while however... about a month ago, she had a giant hole in her elbow area that came out of nowhere.. it healed over, bit there was a hard lump in that same area.... which she is protective of it... in the last few days, that hard lump seemed to disappear, bit that area is now swelling and turning red, and and growing it seems... it's very tender to the touch, and she hasn't been hopping around as much, or eating as much... I did trim some of her fur to see how far or large this is... tell me this is something that will go away on its own, and she is gonna be okay. I'm so worried, PLEASE HELP
