Been having episodes of severe chest pain left arm pressure point pain and neck pain. should i be concerned?

Yes: Although you are young for having coronary artery disease but you never know. I will recommend evaluation by your pcp and/or by a cardiologist.

Chest pain: At 23y/o and female your chances of having cardiac pain are very small. Pressure point pain is almost never cardiac and almost always due to a musculoskeletal trigger. You should not lose sleep over a cardiac cause of this pain. Consult your dr. About what this pain is and how to relieve it.
