To reduce chance of exposing family members to asbestos fibers, asbestos workers are usually required to shower and change their clothing before leaving workplace. The combination of smoking and asbestos exposure significantly increases a person's risk of developing cancer of air passageways in lung. The Kent brand of cigarettes used asbestos in its filters for first few years of production in 1950s and some cases of mesothelioma have resulted. Smoking current cigarettes does not appear to increase risk of mesothelioma.

There is no curative treatment. Close monitoring (routine X-rays or even pleural biopsy) for mesothelioma is mandated. Oxygen therapy at home is often necessary to relieve shortness of breath. Supportive treatment of symptoms includes respiratory treatments to remove secretions from lungs by postural drainage, chest percussion, and vibration. Aerosol medications to thin secretions may be prescribed

Fortunately finding and treating trigger points is quite easy, and you don’t need an expert to do it for you. You just find tender spots which refer pain to your knee when pressed, from those muscles that are reported to be involved in knee pains.

Usually, even a few days of self-massage to those points, can make them stop referring pain to your knee area. And make it evident that they where indeed behind pain.

Finding and massaging trigger points in quadriceps and calf muscles, and small muscles behind knee (plantaris & popliteus), should give you good results.
