I have upper back pain since 4-5 months. I went to many doctors. But all doctor said me muscular pain. My father expired before 7 months suddenly. One of my family MD doctor said my problem is not body problem it is physiological problem. He told me take medicine regular 6 months. DUXEL-20 & ETIZEX-0.25 I thought I have heart problem but I have 3 times 2D ECHO are normal & I also did ANGIOGRAPHY before 4 months, it was normal. I also checked my thyroid & arthritis but its normal. But my weight growing high & now 86 kgs. My blood pressure every time normal, never change it. But still when I feel back pain that time I m afraid so please give me right answer..
