I have very high iron 510plus and other symptoms akin to bronchitis. Please help me with diet or thoughts?

The previous symptoms are perplexing me and so grateful for Canadian HC, but doagnosis is slow and feels like I am being poisoned and my lungs are starting to feel the effects. Small pangs around liver and kidneys and occassional heart pains. I have changed diet and this has stopped the very painful and stringy stools. Always had issues w acid reflux and triglicerides over 400. For some reason tris are normal now> All this adds up to uncertainty about what to eat to lower that iron fast. I have given blood twice and they let me so my iron levels must be getting better. The most obvious symptom is that for the last month plus I wake up every morening with a burning throat stuffed up nose with lots of yellow green mucus and shortness of breathI I even find myself choking like bronchitus and difficulty breathing I finally saw the Hemo doc after my general practicioner agreed the iron levels were scaring her. He saw me quickly and ordered Hemochrom tests and something else but cannot see me till Sept. My weight gain and loss of energy as well as the occasional painful bowel movement is really scaring me. Any thought on diet or how to atleast get rid of this unending cold. I should also point out that I do not have diabetes but the nighly occasional panging pain near ny liver and also kidney areas concerns me. I am also experiencing more noticable burning around my chest and even occasional pangs into the arm. I am 50 and a nonsmoker and nondrinker w a 3 and half yr old son and wife I want to live for. Help!?
