An ulcer that turns watery red does not necessarily mean that it is almost healed, but may be infected by bacteria.
Whether a reddened ulcer is almost healed or more serious should be analyzed on a case-by-case basis. Mouth ulcers are a relatively common disease that can recur and are self-limiting, usually healing on their own after a period of time.
During the onset of ulcers need to go through epithelial breakage, pseudomembrane cover and ulcer epithelium granulation growth and some other stages, in the last stage, the ulcer surface will become red, its surface is relatively smooth, there is a burning sensation to alleviate the symptoms, this situation is that the ulcers have been close to healing.
But the surrounding tissues and submucosal tissues are congested, red and swollen, there will be some inflammatory reaction, its surface will also become red, this situation requires oral anti-inflammatory drugs to carry on the treatment.
It is recommended that after suffering from the disease, should go to the regular hospital for relevant examination, under the guidance of the doctor to use relevant methods of treatment.
