Are nicotine withdrawal symptoms different or more pronounced in someone who has emphysema? - emphysema more condition_symptoms

My mother has emphysema, and only recently stopped smoking. The problem is that since smoking, your health seems to deteriorate. She had problems with pain in the legs (she is also very sedentary, but this is the first time) he complained of pain, it feels much more tired and short of breath and even before, is much more obvious today. The cough is almost constant, and - as she calls it - hard. I am interested in many things in this issue:
1) Are these symptoms are "normal" for the withdrawal of nicotine in people with pulmonary emphysema?
2) Shoud we expect other symptoms?
3) What medications or holistic resources are recommended?
4) Are there can contribute something, * I *?

Thank you for your time!
