I had dental work done today and had novacaine put in my left cheek (5 or so needles worth). It is now 8 hours later and I have a weird feeling in my left arm and would like to know if these two things are related and if it is something I should be worried about. My left hand, especially the knuckles, feel like I punched a wall, pain increases when I make a fist, and the feeling is beginning to spread up my arm.
Thanks for your query, I have gone through your query. The pain in the left arm is not related to the administration of the local anesthesia(Novocaine). For the pain in the arm, you need to consult a general physician and get it ruled out. It might be a musculoskeletal problem, If I am your treating doctor, I would have prescribed an analgesic with muscle relaxant like ibuprofen with chlorzoxazone combination. I hope my answer will help you, take care.
