When you have a dry and itchy throat with a cold, it is likely to be accompanied by a cough, which is an irritating cough, and you can take cough suppressants. If it is just a dry and itchy throat without a cough, it is possible that the inflammation in the throat is present. You may see redness in the pharynx and even swollen tonsils in the pharynx. You may take medications to help your throat, such as Golden Voice Throat, watermelon cream tablets, and pharyngeal tablets.
