10 days ago we noticed some very hard concrete like lumps down cannon bone, now she has more on her one white leg. We managed to pull one off, nearly an inch long, looked full of hair and dry, underneath a scab. Lots of small ones appearing all around white leg now, today knocked maybe a 2inch long one off inside of leg herself and bled. These hard lumps different sizes, her leg has no heat and no swelling, am flummexed!!! Can anyone help?
