Hi, I hope the thyroid functions are repeated and the doses adjusted to the new readings and clinical improvement as hypothyroidism can cause many problems like late healing. Feeling of mucus indicates that there is still hypertrophy of the mucus membrane producing more mucus in response to the healing part and should be taken care by using anti-inflammatory like Serratiopeptidase and decongestants. Have Povidone iodine gargles. Plenty of warm fluids. Avoid hot, spicy and oily foods. Avoid allergens that increase mucus production. As for the chapped lips the cause may be dried up lips hence use lip moisturizer. Continue treatment for anemia if still present and have additional multivitamins, mineral and trace elements for proper healing. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. T. Chandrakant, General Surgeon
