I felt pain on half of my face since last Thursday till now.At first I thought maybe the pain came from my tooth.But after that I found my tooth were quite ok and once I touched left side of my chin and it reflected with pain too.Therefore I think I am having a slight tonsillitis.
Perhaps I was too tired recently or the hot weather caused it.I had taken some Chinese traditional medicine which can be dealt with that illness just now and I will have a rest in this afternoon.Don’t worry,I’ll soon be fine. 
Drink more water and take some rest ya!!!

根据我的经验，如果是厌氧菌导致牙髓感染，就会牵动下巴、脸颊、耳朵甚至太阳穴一起疼痛。因为牙神经没有方位感并具有传递性，因而疼痛会扩散、并且让你不知道具体的疼痛方位。
如果可以确定是厌氧菌感染导致，有如下方法治疗：
1、吃甲硝唑，很有效的抗菌药，但是要注意身体上的变化，因为甲硝唑有可能引起药疹，若发现药疹，及时停药；
2、先锋，广谱抗菌药，可超标准剂量两倍服用，吃多了可能会引起暂时性的肾衰竭，不过是可逆的，因而不用担心。但是要注意一旦上药，就要持续服用，防止体内其他菌群产生抗药性；
3、口含烈性白酒，灭掉口腔内的细菌；
4、三餐之后都要刷牙，去掉食物残渣、防止糖化成分滋生细菌；
5、持续服用布洛芬肠溶片，可缓解疼痛；
6、配备迪克乐可，这是我吃过的效果最好的止疼药，据说是口服术后止疼药，止痛效果是布洛芬的60倍；
7、多睡觉，睡着了就不疼了。
根据我多年的牙痛经验，总结出来以上技巧，希望对你有帮助。多年来我每月都会几天很难过，但是我坚持不去看医生，我有自虐倾向
