I Had A Bad Filling On My Molar Tooth. The

I had a bad filling on my molar tooth. The dentist did not detect it for over 2 months. A change of dentist quickly resolved the issue by removing the bad filling and placing in it's place a temporary filling as I wait for a permanent dentists appointment. So the tooth no longer pains. However, I think the tendon around my neck has been injured and i believe it may be in the process of being healed but I cannot carry lots of things with my left arm, and I am eating soft foods. I do not carry my handbag on that shoulder,so i am doing everything to let it heal BUT i still need painkillers such as ibuprofen (at night when it feels like there is blood flowing through my neck veins and leaving a trail of pain). Sorry looks like i am running out of space. Question is:Can i go for a sports injury massage to relieve my shoulder tension - will it worsen my condition? I know this isn't a sports injury but it might help.
