question: Hi doctor, I hit my elbow a few weeks ago and never really thought much of it. But it has been maybe two weeks now and I still cannot lean on it or touch it in any way. If I do, pain shoots straight through my elbow and down my arm until I even feel a tingle in my fingers. It is not swollen, bruised or shows signs of injury in any way other than the pain. Do you think it is serious and should be checked out, or did I just hit it hard enough that even though there is no marking, it is just sore this long?
