<s>[INST] I had all four wisdom teeth removed 3 weeks ago and for the past week have been getting very severe tension headaches are the two things related.The oral surgeon said it was a very difficult extraction as they were all impacted.  My jaw still aches and I havent regained full range of movement yet [/INST] Hi! Welcome to Chat Doctor. I read your query. Post extraction of impacted teeth, there can be discomfort for following month. There can be pain or numbness or restricted movement of jaw due to nerve injury during injection or extraction. However, it reduces and go back to normal in 2-3 weeks. As for your headache, post extraction abscess or misalignment of jaw can lead to headache. I suggest you visit your oral surgeon and get checked if there is some secondary infection or MAL occlusion. Ask him for oral exercises for stretching and opening jaw. Do warm saline rinses. Relax oral muscles by putting a warm cloth from outside. If after all corrections headache persists, contact your physician for further investigations. Hope the answer helps you. Thank you. </s>
