Hard Phlegm: The most important factor is hydration. Take plenty of clear water and use a humidifier next to you, you can also take decongestant but avoid cough suppressants Another type of medication that is helpful is an expectorant such as Guaifenesin that loosen phlegm. This medication is available in over-the-counter products. Also what may feel like phlegm may be localized swelling.
