Follow-Up:
My lips are chapped, swollen and raw, I could hardly open my mouth to eat. My gums hurt too when I brush my teeth. This is the third time in less than a year that I had this and I believe I found the culprit! It's the toothpaste Sensodyne that my dentist recommended to use for sensitive teeth. I never had this problem ever before until I started using Sensodyne. I should had made the conection from the first and second episode, both after using the toothpaste within 4-5 days. The third episode came after only 2 days of using it. I believe I have severe allergic reaction with that toothpaste. Anyone who have similar symptoms might want to check what they are using for oral hygiene or what they putting in their lips/mouth. Me, I'm on my way to my doctor to give me some relief for the discomfort because this will last at least 2 weeks.
