I would return to your dentist for scans and x rays of both the teeth and sinus cavities. The fact that your gum swells up monthly indicates that you may have an abscess and if this has broken into the sinus cavity then this can give rise to the symptoms that you are experiencing at the moment.
Ibuprofen 400mg three times daily would be my recommended painkiller as this reduces swelling as well as pain. Rinsing with salt water may help drain the abscess. But if it is an infection then you will need antibiotics.
