 [ Symptoms ] for shoulder pain radiating down arm is heat or cold better  after working out with a trainer that night my arm kept me up most of the night with throbbing pain especially around the elbow during the day pain is not bad at night it is terrible taking alieve not sure if i should put cold packs or heating pad on arm [ Disease ] you ask a fascinating question and one that is very worthy of discussing with your dad is physician i tried to search for some relevant studies on this topic and did not find very many in general people with copd do worse at high altitudes whether they have lived at altitude for a long term or not the issues with ventilation at altitude are more complex than simple oxygen delivery there also are issues of breathing mechanics and heart function that come into play all of this is not to say you should not move your dad to be with you in denver i am saying it could be manageable if you discuss it in advance with some good doctors and learn what things you need to do to manage your dad is condition at high altitude or you might both decide the risks are too great my personal opinion is that quality of life matters more than quantity of life    especially when a person reaches an advanced age i would suggest you consult with your father is doctor or with a physician in denver to find out if the benefits for your dad would outweigh the risks wishing you well
