I have been getting these lingering and sharp pains in my left breast for 3 months now. they are very uncomfortable and i seem to have them now every day. I have been told i could have Costochrondritis and in the Past month i have had 3 ECG tests all normal. i havent really had any other tests I could be sitting there then i get them really bad. I would like them to look further into the problem but i just dont know what to do anymore Could this be a Possible Panic Attack?? I have tried herb tea BAch remedies ETC nothing seems to help also they seem to get worse in the evening. Please advise
