bacterial infection
"Was prescribed clindamycin today for an abscessed tooth. I am waiting to get a root canal down on a bottom molar (2 weeks from now!). During my waiting process, my tooth became infected. Had tried amoxocillin, which failed... And then  the right side of my face started to swell and that's when the PAIN became so bad I ran to the emergency room. I took my first pill a couple of hours ago but haven't noticed a difference. Haven't had any heartburn or any other side affect. I took some oxycodone and ibuprofen about 20 minutes ago, I think it's starting to help. I hope this works! Keeping my fingers crossed. I can't take one more day of this terrible, excruciating, head-banging on walls-throwing objects across room PAIN!"
