ICI discussed a versatile foam technology based on MDI that reportedly can be tailored to meet car makers' requirements - from durable, low-density foams for North America, to high-density comfort foams for thinner seat cushions in Europe, and high-resilience foams specified in Japan.
Pain arising from other organs may be felt in the back. This is called referred pain. Many intra-abdominal disorders-such as appendicitis, aneurysms, kidney diseases, bladder infections, pelvic infections and ovarian disorders, amongst others-can cause pain referred to the back. Other skeletal causes of lower back pain include osteomyelitis, sacroiliitis, and osteoporosis vertebral fractures. 2  This pain is often worse at night and when sitting or standing for a long time. 3  Tumours, possibly cancerous, can be a source of skeletal pain in the back.

Interestingly, the lungs themselves do not have the type of nerve connections that induce pain. But the lining (pleura) around the lungs may be associated with pain if it becomes irritated or inflamed.
