Did you ever find out? I am having the same problem on my right side. My breast and shoulder blade have like a raw,burning,numbness. Like if you have a sunburn when you touch it.
Why Do I Have Tingling And Numb Feeling Around Left Breast And Shoulder Blade?
How much activity r you having? Do you have peircings? Everything isn't for everyone. Check the position on sleeping. Do a breast exam.
