Hi, thanks for sharing your health concerns with HCM!
If I were your treating Doctor for this case of gum discharge, before commenting anything I would like to know the duration of this and also any kind of tooth problem...
However, in present case, I would come up with three possibilities, these include:
1. an infected periapical or periodontal cyst
2. The second possibility is of an abscess
3. The last possibility is of some lymph
collection or infection!
Overall, it is benign or infective and not to worry about this but you could go for OPG and microscopic test of the discharge for confirmation if still worried!
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
Wishing you good health.
