Chest & Breathing Problems

Hi. I was a smoker since 4 years..I left smoking in March. But then last weekend and a weekend before that..I had one ciggerate. Not in between. After that I guess I was feeling some congestion. don't know if it's related. But my major problem is when I sit taking back support I feel like by chest and throat is squeezed. When I remove the support I feel ok. Few days back I was having gastritis.. I am worried... I showed my family doc . He just prescribed me throat infection medicine.. laboclox lb..and his local medicine.. Please help

Mostly at night sometimes i feel shortness of breath and little heaviness in chest not pain...this happens two three times in a week happening since 3 4 days ...what should i do and whom should i consult?
