I'm having a sharp pain in my elbow. it hurts whenever i straighten out my arm and then try to bend it after. mostly around the top part of my elbow.

Get examined: sounds like olecranon bursitis; however, requires an exam and probably an x-ray.. OK to use Advil or Aleve (naproxen) if not allergic to these medications and call for an appointment- TODAY!

Tennis elbow: History of repetitive recreational or occupational activity. Elbow pain during or following flexion and extension. Pain at the lateral aspect of the elbow. Try Rest, ice, NSAID, brace /strap. Avoid activities that exacerbate the pain. If no response to therapy after 6 weeks, Go to doctor.
