I am a 42 year old woman that has been experiencing ches pain for over a week now. It came on all of a sudden in the afternoon, after eating Soup, salad and breadsticks.The pain was so intense that it made me very tired.I thought I had a pulled muscle or upper chest infection. After six days I took myself to the ER. They got me right in and did and EKG and blood work.All the test came back normal.The only symptoms other than pain, mainly the right breast, is pain when bending over and the breast feels swollen and tender from the armpit down.The pain gets worse if I move a certain way and it has been difficult to sleep.My last mammogram was summer of 2010 and pap.I do not know if this could be cancer, skeletal or muscle. Any insight would be helpful.
