Brief Answer: Antihistamine, NSAID, Steam inhalation, gargle Detailed Answer: Hi, thanks for using HCM. I went through the query and understood your concern. Based on the explanation you may be suffering from sinusitis and hence post nasal drip. Yes due to inflammation the mucosa in throat may be swollen and will affect your voice. So you can use antihistamine drug like loratidind or levocetrizine to reduce secretion and also NSAID like aceclofenac to reduce to inflammation. If the secretion is very thickened then the antihistamine should not be used. Also if infection (associate with fever or pain) you may require antibiotic for its management. Along with the drugs do steam inhalation and clean your nose that will clean your sinus and salt water gargle to reduce throat inflammation. These measures along with the explained drugs will help to relieve from your problem. I hope this information helps you. Feel free to ask if any further queries and I will be glad to answer them. Wish you and your family a very happy life and good health. Regards
