I am going crazy My nose is constantly blocked but with a slight trickle and I always have to blow it but to no relief. I'm starting to get headaches from it. My sinuses are all blocked and stuffy and I'm so irritated. All I've tried is Lemsip and it did nothing. I have some Dimetapp but it's categorised as a Class B drug so I shouldn't take it

Please help me!! Does anyone know what is safe and effective to take?
