Hi I read this while searching for some answers. Since you have had copd for 2 years I wanted to ask if one of your symptoms was excessive sweating? None of my doctors can figure out what is wrong but I just had a pft which is abnormal. It shows obstructed airways and decreased diffusing capacity (whatever that is). The sweating has been getting worse for about three months and no it's not the heat or hormonal. Please let me know if you had a similar problem. ThanksView Thread
