To start off I'm a 48 years old some what over weight (260). I've started walking and lifting small weights again. Two weeks ago I sat down to eat supper and I got one bit down when my left shoulder started hurting so bad that I could not eat. I took a Advil (800 mg) and got by the night. This pain comes and go's but not as bad until the last two nights. This pain is now moved to my back and rib cage under that left arm. If I breath deep or cough it fells like a dull knife jabed my ribs. Theres very little pain when I stand but, who can stand all night??? I started to go to the ER but I didn't want to pay the $200 office call. I'm trying to wite until Monday morning. I was thing this may be plurasey but my wife said something about a blockage. Have any of you had this and what was it????
