After root canal

[Margot49]

Long story, but had a root canal done yesterday on upper 12' I thunk it was.  Tooth had been hurting for some time. The dentists I went to said nothing. Told my ENT doc about it and he put me on Keflex.  Went to another dentist for cosmetic consult. He said it was infected and I needed treatment.  Anyway, had a root canal yesterday.  No swelling but still pretty sore today, like it has been.  Doctor put me on 7 days of Clindamycin, 150 mg 3x a day, which is a pain to have to take every 6 hours. Read about side effects but none so far.
I am wondering why the Keflex didn't help
Has anyone taken this med before ?
Doc's office discomfort is to be expected but thought it would feel better after the root canal and still feels the same, ESP if I press on it.
No swelling or fever

I am having the same problem after root canal. When I bite, I feel the tooth is a little bit higher, especially on the edge. Will go to my dentis tomorrow and get it grinder a bit.
Fingers crossed!

Oh. By the way.. About Kelflex and amoxicillin. I took both of them as well. At first, Kelflex does not help, so my dentist changed to amoxicillin, which solved the problem.

My mom (she is a surgeon) said these two antibiotic are treating different bacterias. It really depends on what bacteria you caught.
Hope it helps. Also always finish the whole course. Stupid me. Last time I stopped when the pain subsided, and of course it soon came back!

P.S. I live in Australia.

Thanks for the response.  Got sick again a day short of finishing the antibiotic and the dentist and my GI doc told me to stop it.  Endodontist checked the tooth and guess it is just sore.  Went to the dentist that is planning on trying to do bridges and he did some grinding on the bridge I have now to take the pressure off the bite and it feels much better. First time in a loooong time I have been able to bite down on my own teeth without discomfort..  Still a little sore above the tooth but mot as bad. Just hope this works.

Even after RCT the tooth may still be sensitive for a while. It can take a few days for the antibiotics to get into your system. Do make sure you finish the whole course. If you are still in pain after a few days, go back to see the Dentist. If the pain does clear up after the antibiotics, make sure you tell your Dentist at your next appt that you suffered even after the RCT had been done.

Hope this helps

Bad day today.  More sore and upset stomach, add that to worse dry mouth and throat issues and again producing phlegm.  Called the dic who wants me to try and stay on this med. every 6 hours is a problem. Makes me sucker having to get up at 5:30 Am to take a pill and drink a full glass of water.  
Never this miserable after a root canal before. He said the infection is probably in the bone.
Anyone else have these issues? I asked for maybe Keflex but he said this med is better.
7 days of this!!
Now, for some reason, a bottom molar is hurting
