I am a 32 yr old female. I have had recurring chest (aching pressing pain) on the left side and left armpit for months. Sometimes I also have pain in my breasts, other armpit, left arm, left side of my neck, jaw and left cheek. I went to the ER for sinus tachycardia in January 2008. At that time the chest x-rays and angiogram were clear. I had slightly elevated white cells but otherwise the bloodwork was normal. EKGs were also fine. A 48hr holter moniter two wks later showed only occasional ectopic beats. The cardiologist I saw said that chest pain for someone my age isn't that big of a deal. I have not had any heart or respiratory symptoms since January but the pain persists everday to some extent. I have been trying to follow an anti-inflammatory diet and have been getting acupuncture. I wish I knew what this was so I could try and get rid of it.
