I had cavity in my last lower left side teeth. Last 2 days I am having unbearable pain with swollen gums around that tooth. Doctor gave me Lysoflam and Moxikind CV 625. I have taken 3 doses, but the pain still is unbearable. Doctor has recommended root canal treatment. But currently my pain is too much and unbearable. Pain is relieved for 3 hours only after taking Lysoflam. Can I take Lysoflam at 3 to 4 hrs interval? Also can I take Ketorol DT 2 10mg 3 to 4 hrs after having Lysoflam ? ( I am addicted to chewing tobbaco, and have submucos fibrosis)
