Is Pain In Back,neck And Allover Sign Of Heart Problems?

I have been in pain for some years now with pain in my neck, top of my back, sometimes arms, elbows, wrists, lower back very much so, knees, ankles and balls of my feet, also I have abnormal stools for a few years now they are paste like. I ve had an MRI scan they did find a bulge impingement and something to do with my nerves endings, then the bulge went away but not my pain. I keep going to the doctors but feel like he s not listening. I expect it s because when I do see different surgeons nothing is coming back really positive. My blood pressure is often very high and i am on Ramipril 10mg once a day and Bendroflumethiazide 2.5mg once a day. Rencently I ve been having tightness right acrost my chest under my bust and down my left arm but apparently my heart is ok. I ve had three brothers die of heart problems ages 7. 23 and 47 years old. I don t know what to do because I am in constant pain though a few days ago the doctor did give me Codeine Phosphate paracetamol?
