I am having a hollow feeling in my breastbone area through to my back. Feels like the pain is in between my spine and left shoulder blade. It s making me feel breathless but my pulse ox is good. I have issues with my back but I am terrified that this could be a heart issue. Feels like I can take breath and the air just goes around the pain area. Thank for any info, Carla
Hi I am Chat Doctor. .  In my opinion i don't think you need to worry as heart diseases or heart overload may send a kind of referred pain to your left shoulder and very rarely towards your back as long as your pulse oximeter is good with normal pulse and oxygenation.  Actually this could be a kind of muscular sprain or spasm that is relieved by hot massages with topical gels containing anti-inflammatory and muscle relaxant actions from OTC. For my patients I may suggest X-rays and MRI for proper evaluation and management. Please click THANK YOU and consider a 5-star rating with some positive feedback if the information was helpful.
