collapsed lungs. i have thrown up twice tonight and i have very bad tightness in the chest but my nasal and throat are clear. i have just started on patches to help me quit smoking and I'm an asthmatic but atm it feels like no oxygen  is staying in but i have a pulse, and i also have been suffering anxiety, is the patches affecting my asthma and breathing?
What are the side effects of [nicotine patch]?  ALT: What triggers asthma?
