I am a healthy 50 year old female. I am recovering from a cold virus that lasted 3 weeks (this is week 3). Last night I had a bad headache and went to bed early ... around 2am, I had a sharp Charlie horse or contraction like sensation/pain in my RIGHT chest. I felt pressure and it radiated to my esophagus area. This pain was sporadic and would only last a few seconds, then subside. It did not matter the position I was in, or whether I sat, laid down, stood or walked.
