<s>[INST] I recently had an infected tooth and couldnt get in to see the dentist for two days. My bottom right lip and cheek began getting numb....I ended up having a root canal which went fine. I still have numbness and swelling in my lip and gum area. I have been on Clindamycin 300 mg over a week and have began a second round plus received an injection of an antibiotic in my hip to clear up any infections which may be lingering. Im getting concerned this is lasting too long especially since Im taking antibotics. Any suggestions [/INST] Thanks for your query, I have gone through your query. The reason for swelling could be because of the persistent infection or its relative feeling of swelling secondary to the numbness. The numbness in the lip and chin could be because of the trauma to the nerve during injection of the local anesthesia, or it can be because of pressure caused by any cyst or tumor on the nerve ending. Clindamycin will clear the infection, but it will not solve the numbness problem. You can take nerve regenerating Chat Doctor.  But you have to rule out the cause of numbness so consult your oral physician and get a radiograph done. I hope my answer will help you. Take care </s>
