I have itching inside the inner back throat from around 6-8 months and I cough sputum regularly(no blood).Also frequently my tongue sides get red and pains. I consulted a general physician for this.He prescribed me Jecfen-M (fexofenidine, sodium and montelukast) and V-flo tablets.But still its not working.In past, I used to smoke cigarettes,(for nearly 1 year) but since 3-4 months I already stopped smoking permanently. Please help!
