question: my husband has been having a number of symptoms for several months and although under the care of a doctor, testing and results of testing are coming very slowly and we still have no diagnosis so I was wondering if you might give me some advice. He is 45 and a smoker, weight is 350, height 5 11. He has high blood pressure that is being treated with medication. He has sleep apnea, which he has a cpap machine for. In addition, he has shortness of breathe somewhat controlled with inhalers. Recently he has developed lower leg, ankle and foot swelling and has been given water pills for that. He has an awful cough and can not lay flat at night. He tires very easly and needs to rest during his daily higene routine. He has in the last few months become unable to work due to tiring so easily. He had a lung function test this past week but was told his follow up appointment will not be until mid december. I am very worried about him and need to know if I should seek the advice of another doctor or just stay patient and wait on the doctors we currently have. I guess what I need to know is if he is in real danger.
