Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
It is most probably an infection probably an abscess
which has fibrosed over a period of time. If the pain has gone down then the things will improve over next 2 weeks. However if the pain is still continuous then you will need antibiotics like cefexime. If the pain persists then it may be needed to do drainage
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
