I have persistent pain in left breast burning in sensation, somehow pain in armpit, left side of back, left arm and pricking pain medial to left breast?

Complicated case: It looks like you are having a neuropathic pain from the distribution of your pain. In any case your presentation is a bit concerning and advise you to see your family doc so that you can get the assessment and treatment. Best wishes

Need eval: It sounds like nerve irritation (neuropathic) pain but it would be difficult to clarify. As a very young woman breast cancer is unlikely but not unheard of. The distribution of pain is unusual but may be coming from neck. Also if there is a rash present you have to think about shingles- go see your physician.
