I had a sudden onset of sharp pain under my left ribs increased pain with palpating, and radiates into my left shoulder blade, I was working out today thinking it was muscular but the pain hasn't subsided with heat or rest, took tornados 10 mg pain decreases when standing, lying on the effected side increased pain. lynwit@ hotmail.com. I am a nurse working at an outpost station, no hex of mono, or blood disorders may be muscle but nothing is relieving it pain 7 out of 10, intermittent sharp pain take your breath away. Thanks otherwise healthy ECG NSR rate 86 so stern all pain or pressure, fullness in abdomen
