I was bit by a dog 14 days ago and the area seems to be healing but i noticed a hard lump in the middle of the bruise and the bruise itself is hot to the touch. The bruise originated back of my arm above the elbow at the bite site, has spread down past my elbow and has almost wrapped completely around my arm, i feel small spasms every now and then in my fingers and if i bend my arm i get pinching pains in the elbow and shoulder, could this be something serious?
