hello! My age is 24, I'll be 25 this August. Something is bothering me. I started smoking 12 months back, and I smoked about 2 cigarettes a day. Now it considerably increased to 5 cigarettes and I have cough that wouldn't go. Also, I have two patches on the either side of my inner cheeks, one is blackish (no pain, no swelling), and a scratch kind of white line on the other (no pain, no swelling). I have been coughing regularly for 25 -30 days now and have this strong urge as if there is something that's caught in my throat. Mucus is been produced normally out of cough. Two days before, I consulted a dentist and he said there's nothing to worry. I am taking antibiotics now. Some relief is there but i don't understand what is this. My tongue has few cuts fro the past two days and has this strange burning sensation. When i scratch these cuts, blood comes out (but very very little, as these are scratches that may have caused due to hard brushing that I do). Mucus is producing, I am clearing my throat every time i'm coughing. I'm spitting it out. My throat is not comfortable these days. But since the time i have started taking medicines, amox and citrizine, it has gone a bit better. I'm 24 smoking from 1 year, almost 4 cigs an average, should I worry??/
