I am experiencing a pain in my left arm running from the middle of my arm through my forearm and into my fingers. The pain resembles an electric shock and is continuous. It is not my entire arm, but deep within it. I am a male, age 48, 6 10 and 250 lbs. I had a pericardial effusion about 5 years ago, but no other heart related illnesses. However, cardio issues do run in my family. I have been a nonsmoker for the last 5 years, since the illness mentioned above. I have taken a 325mg aspirin. I use Prilosec OTC once daily for my acid reflux, but no other meds or known medical issues. I am unemployed/uninsured, so going to a hospital is a big decision. So, I am asking an opinion first from you.
