my husband is 65, in his back especially just below his left shoulder blade near his spine he has been getting pain every evening around sunset. He does have a herniated disk in that area. The pain hits and goes from about a 2 to a 10 within about 10 min. He talked to his doctor who prescribed tramadol. This does not seem to help much. He tries hot showers, keeping a warm heated blanket on it. If he takes the blanket off just long enough to go to the bathroom the pain will start. Any ideas. Could he be having a heart attack because his heart does start to race and the left side of his chest starts to hurt. No pain in his arms.
