I have experienced chest discomfort (in different spots) and discomfort in my shoulders, arms, and hands.  Kind of a dull ache that comes and goes.  Some shortness of breath.  My blood pressure is great, and my chest x-ray, EKG, and CT scan came back clear.  My d-dimer is somewhat elevated but stable.  Naproxen has decreased my symptoms considerably.  The doctor thinks it may be costochondritis.  What do you think?
Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about major heart or lung related diseases because your extensive work up for these diseases is normal. Yes, Costco Chat Doctor.  You should also get done vitamin D3 and calcium levels because deficiency of these can cause similar kind of pain. If deficiency then you may need supplements too. For Costco
