Hello, approximately 2 weeks ago I was bit by a dog on back of my arm, right above the elbow. Most of the bruising has faded. It puncture wound is still healing. But under my skin, maybe into the muscle, there s a hard lump that is painful to the touch. It radiates about an inch and a half from the puncture and is about and inch wide, and at the bottom of the lump is another thin line of something that feels kind of swollen. What is this and will it go away? Thank you for your help.
