- Redness and swelling: inflammation, allergy
- Dark yellow urine: dehydration
- Toothache and sore throat: physical damage (burns, abrasions, etc.), chemical irritation, biological imbalance (pH, microbes)
- Nosebleed: consumption of anticoagulant foods (such as theobromine)
- Lip blisters: herpes virus outbreak caused by stress, sleep, etc.
I recalled a very effective prescription for oral ulcers: dexamethasone (anti-inflammatory) + lidocaine (pain relief) adhesive patches, but this is only suitable for short-term occasional ulcers. What about recurrent long-term ulcers?
