I have pain in left breasts and chest, also in arm pit and shoulder along with pain under shoulder blade. Sometimes it hurts to take a breath. The shoulder has been bad or over 6 months ,the other things started about 3 months ago and are very bad now.
For this you need to get evaluated by a GP however just from the query what I can make our is that you are having the pain radiating from your shoulder problem. Hot packs will give you relief to some extent and doing basic shoulder exercises will help in maintaining you range of joint movement. Hope you find this helpful
