i'm voting for "doctor-worthy. " what your describing could possibly be the formation of a hematoma which is basically a large bruise. however unlike superficial bruises hematomas are sizeable collections of blood that can become infected if not treated. that's why i'd recommend you get this checked out by a doctor. at best it will turn out to be nothing and you'll have peace of mind. it seems like a can't-lose scenario to me. good luck to you!
i recently got bike handle bars to the lower abdomen and now have a hard rock like tender spot forming. what to do? . it has been just over a week since the crash it has been tender since then but the rock like formation did not start until 3 days later and has gotten what seems to be larger and harder. just a change in the connective tissues? or doctor worthy?
