No Smokers Cough / Urine Leakage / Weight gain

Last Aug-this January I quit smoking. When I started again it seemed like after a month or so I didn't have a smoker cough, normally that would be a good thing but I still feel like i'm so congested all the time but can't cough anything up (as nice as that sounds) and have had so much chest pain, but already had an x-ray and nothing was showing. My tongue was been white 1/2 the time lately and gums sore. I have to wear panty liners 30days/month and only in my twenties.

Any suggestions as to what gives? and what it may be...My doct still thinks it's IBS...oh and I've been constipated...like the usual...the last three years...
