A couple weeks ago I got a saddle horn from a bucking horse in my upper thigh. It turned out in a big bruise. There is a spot that is numb and it had a hard lump in the inside. Since last week there is a bump coming up and it hurts now more than in the first week of the injury. It hurts when the place get stretched, so in every step I walk it feels like some tears open. It's really uncomfortable. What is it or what can I do about it? (Lin, 23yrs old, 175cm, 60kg, no medical history)
