I am 41 years of age. I have pain in whole body almost. For quite sometime now. It pains in the neck, shoulder, arms, back, waist and also in the arm and leg joints, elbows, knees, ankles etc. Also feel headache at times. Can't sit straight for long as back pain starts and even can't keep knees folded and sit for long as it starts paining. I am also having tremendous weakness as if I will fall done at time. Feel shortness of breath sometimes and chest discomfort as well. I cant walk much faster and long as feel tired and distressed. I have done several diagnosis related to heart and shown cardio but as per doctor I don't have any cardiac problems. I am also going through tough time professionally and financially for last few months now. I am too worried about my health and can not concentrate on anything else due to this. Please help me to get fit and healthy.
