Hi, I have a question, I fell on some steps about ten days ago, I went to the Doctor, about a severe painon my right side of my body, Doc suggessted since the pain is deep and their wasn t any bruising where I was hurting, that I may have a blood pocket and that he wants to do an ultra sound, however, the pain has not gone away but is tolerable. Do i need to get an ultra sound anyway and see why the pain is still active or forget about it and see if it heals on its own? and or go back to the Doc if it gets worse?
