Could this be Costo

Hello-
New to the forum but have been researching what this pain I've been having for over a year could possibly be and I think it's Costochondritis. Perhaps someone who has been diagnosed can tell me if the symptoms are similar. I have a pain on the left side of my sternum, right where it connects with my breast. I only feel pain on my left side. Sometimes it is an ache that is only felt in that area. Sometimes I feel it in in my back. Also I feel soarness in my neck, shoulder, and most recently pain in my breast and armpit area. It seems to be getting worse with time. I have seen doctors with no diagnosis. I have had X-Rays and Blood work all coming back normal. I tried prescribed advil treatment, I hate taking pills so I was not as conisistent as they had prescribed but noticed it helped with all the referred pain but not the peircing like ache in my sternum. I am 16 weeks pregnant and it seems to have become so much worse now. There was one night I probably should have gone to emergency but I just knew this wasn't my heart or lungs. The pain was so bad I couldn't lay on my back or left side. Like something in there was very swollen. Yet, tt doesn't feel like my organs. I don't have any signs of such, no shortness of breath, no tingling sensations, no coughing, no palpitations, no vomiting (well actually only that related to morning sickness) and EKG's have been normal. I do have some GI problems but I know this isn't reflux. Since the pain has become worse, I have been able to finally pay closer attention to when it happens, and it always flares up when I'm stressed, after I pick up my 2 1/2 year old, or when I've been working on my computer for long periods of time. Sometines, it just acts up becuase it feels like it too, and that is usually when my mind starts to convince itself it something much worse. I want to schedule another doctors appointment but I want to be much more prepared this time around. I have wasted so much time relying on the doctors to figure this out for me so I want to go in to my next doctors appointment with my own research in hand. Anyone who could offer any advice or support, please do. I feel like the pain is starting to take over. Thank you! Tweet
