Im having pain at left side of whole body top-bottom what is means and what it causes pls tell me?

Are you an Athlete?: How did the pain begin? have you exerted recently or fallen down? Try taking Tylenol (acetaminophen) or Ibuprofen 3/day for at least 3 days for symptomatic relief. If not associated with Fever, skin lesions, Arthritis- this sounds like Muscular pain. Cannot diagnose the cause with the information you gave. If it has been more than 2 weeks duration and not responding to OTC meds, you should see your PCP.
