My belief is asthma is alelergy of lungs. Same allergies in other parts of the body are named differently. eg. allergic conjunctivitis, rhinitis, pharyngitis, laryngitis, tracheitis. I also belief that the allergies in muscles causes myalgia, in joints causes arthralgias and arthritis. Skin eczzema is also somehow related to it. All of these can, should happen in the same person, may be at different times, usually unpredictable for time of onset and severity. Genetic factors are definitly related, but sometimes no family history is found. May be its incidence is increasing
