Old Cough and cold poor digestion. Help.

I am 32 yr old, weight is 70 aprox, and height 5ft 10inches. I have old cough and cold since childhood. Presently it is troubling me very much. My nose, one side always remains pack due to cough. I feel heavy cough in my throat. Often feel headache during cough and cold. Area of headache is generally behind the ears and back side of neck. Alongwith this I have sneezing problem too. Cough get worse when I sneeze. Usually sneezing happens in morning, and the times when I get out of somewhere like home, office, cabin, car. Medicines like trikatu churn, shitopalaadi provides relief but it increases constipation with hardening of stomuch and gastric. I have little constipation too. Most of the time having high amount of shitopladi or trikatu churn, or taking allopathy medicine like citrazine affrects my sexual health as well,and made me pee with higher frequency. Please help.
