I quit vaping in April by.putting.on the patch but a week later I stopped using the patch too and quit all nicotine cold turkey. For about a month, I experienced nothing related to coughing and gunk you hear about from quitting. Now though, for about 10 days...a dry cough started and in the past few days is more frequent and my chest feels like it wants to clear stuff. My chest hurts a bit too. I have no shortness of breath and am still able to exercise. I am scheduled for my pft and my chest feels a little congested. Not sure if I neee to call the doctor due to possible infection or is this normal with quiting. What about the impact on pft? I am coughing now..not throughout the day... but I have a few bouts of coughing that seem.closer and closure to being productive.... I also clear my throat a lot more. My husband thinks it is par for the course and my chest pain is nicotine withdrawl. Is this normal?
