hi there.  i fell down some stairs about 4 days ago.  the main areas hurt (with hot to touch bruises), are my right elbow, and very top of my right buttock.  about a week prior to this, i was bending under a table, and when i moved to get upright again, i smashed my tailbone into the corner of the table.  the buise for that has just about disappeared. ive started getting an odd pain in my abdomen (right side).  its not a contstant pain.  it comes and goes every minute or so.  its fairly sharp - but not a terrible stabbing pain right now. i feel healthy otherwise.  im taking a couple of asprin a day to avoid any clotting. whats the abdomen pain about do yoyu

### output:

Hi. Thanks for your query. Fall from stairs certainly cause such injuries that can become obvious only after some days. Yours are at the right elbow, top of your right buttock. As I told just now that some injuries can become obvious only after some days and hence tries to neglect the proper examination by a Doctor and the investigations. Since you have a pain in the abdomen, again on the right side. This is not constant, comes and goes, and is fairly sharp. I would advise you the following ::First stop Aspirin as it can enhance your problem by causing or increasing internal bleeding by virtue of its antiplatelet activity. Secondly, get a clinical / Physical examination by a Surgeon for proper clinical diagnosis. Thirdly, go for CT scan of the abdomen to get the details whether there is any internal injury to the colon, right kidney, liver or so. If found get admitted for under-observation and review of the condition as you may need surgery any time. IF normal, nothing to worry as this can then be just a bruised abdominal wall muscles.
