I have covid & recovering at home, i'm taking mucus medication to loosen the mucus but now that it's loosen it seems to make my chest tight until i cough, however it doesn't allow me to spit it out as it just stay in my throat. should i be worried?

Water intake: The key factor when taking mucolytics is water intake. If you take a mucus medication but do not increase your water intake, it tends to make you a little dehydrated. Increase your non caffeinated fluid intake so that you are taking at least 3.5 liters in a day. This will allow your body to recruit some of this liquid to make your mucus thinner and easy to spit or cough out.
