Went camping last week and the last few day my middle back between the shoulder blades tightened up really bad and now I have pain there daily and it sometimes radiates to the front of my chest.
I have had this on and off in my life, but this is the worst it's been.
I really notice it when I take a deep breath in. Last night I went for an hour walk and the whole time my middle back ached and I felt it in the chest as well. Then I got a headache by the time I got back.
Went to the chiropractor a couple days ago and no relief.
Any ideas of what this could be?
