 [ Symptoms ] 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 [ Disease ] i am 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 is why i would recommend you get this checked out by a doctor at best it will turn out to be nothing and you will have peace of mind it seems like a can not lose scenario to me good luck to you
