Welcome and thanks for posting on HCM
Just wish to know how long the most has been there? By scratching you created a way for infection and now you are just suffering from inflammation due to the presence of the infection. I suggest you get medical attention any of these days. You might require antibiotics locally on the mole or your doctor will give the best possible treatment after evaluating.
The main reason for immediate medical attention is to avoid unnecessary complications local or systemic. Either way it will not be good for you.
Just see a dermatologist
Hope this helps
